I got my Pixel yesterday and was very excited to get my hands on it after hearing about the amazing battery life from those in the shop and on online reviews. The battery life was the main thing that pulled me in over the Samsung Galaxy S8+, but I'm not sure it's all it was hyped up to be so far! Day one with the phone, it was at 100% charge when I left the house this morning, within 5 hours it was at 60% and within 6 it was at about 52%. I checked my battery usage, the only apps I'd used were Apple Music which took 16%, messenger which used 5%, and Facebook which used 2%. All tabs were closed after I'd finished with the app, also. After seeing this, I was really shocked as to why it has drained so fast, considering I was told with light - moderate use it should last all day easily. Is this the average battery drainage or could something be up? It's not the worst battery I've ever had, but certainly isn't the battery I was expecting given how much the people in the shop/in reviews I'd seen had praised it.

New phones or reset/cleared data/cache(rom flash, kernel etc.) need several days for the battery to calibrate. Give it some time to adjust, also could be settings or rogue app that is draining the battery. If it doesnt seem better you can use BBS(better battery stats) app or similar to see exactly what is going on
Just to clarify you're talking about a pixel XL 2, as your title suggests? Just a bit confused as you've written this in the pixel 2 (non XL) forum.
For what it's worth though, I had a pixel 2 XL before my current pixel 2 (I moved just because I wanted something slightly more bitesize). In terms of screen on time I would quite easily get 6.5-7.5 hours on the XL all on stock and it just seemed to keep on going. My pixel 2 is also awesome albeit doesn't last quite as long. I'm currently on 17% and I have 5.15hours of screen on time. I've also used over an hour of Spotify with streaming over Bluetooth with that - so it definitely is good. It's also early days as this phone is new!

Careful with that battery usage. The latest word I've seen from Cadex is to keep it between 40% and 90% (or a little less if you can) for longest life. And with a non-removable battery, that's probably what most of us want. (IOW, latest tests show that even if we give it more charging cycles, it lasts longer if we don't go too far up or much below half down. 17% might give you props, but it won't give you a great battery in 3 years.)

Thanks, appreciate the tips - but bear in mind this was just the first few days of having the phone and it does typically represent my usage. If I charge once a day from around 10-30% to 100% of course it's naturally going to degrade. Bit by the 12 month mark, but likelihood is I'll have the pixel 3 then so it doesn't bother me too much!
One of the things that convinced me to bite the bullet was that the P2 will be supported until R (raspberry-something?), so I'll still be up to date almost 4 years from now. (I don't even have a fingerprint reader on my current - and flagship - phone, but by 2020, I might just be ready for the Pixel 4 or 5.)
(And to think - I used to be a dealer walking around with 4 phones on my belt [we sold 4 carriers] and I'd think nothing of grabbing a new phone as soon as it came out and using it until something nicer came out - now I wait 4 years to upgrade.)
And with the 2 year warranty, the phone might be replaced

For a short battery life? Batteries are consumables (and you can kill a completely good battery in a month by treating it wrong), so even a battery that throws a dendrite most likely wouldn't be replaced (and that's not only a manufacturing defect, it's a defect in the technology itself).

Do you have the reference for this? 40% - 90% is using 50% of the battery capacity. If that works for you, the chart below would suggest a range from 25% - 75% would give optimal number of cycles, unless I'm reading it wrong. It seems it's the higher % of charge state that stresses the battery most.
The chart below comes from here http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

First, that's for a 1C charge - cellphones, even Quickcharge 3, don't get near that. (A 1C charge would be charging a 3000mAh battery at 3 Amps).
Second, I use Cadex' chart from the same article:
Table 2: Cycle life as a function of
depth of discharge. A partial discharge reduces stress and prolongs battery life, so does a partial charge. Elevated temperature and high currents also affect cycle life.
Note: 100% DoD is a full cycle; 10% is very brief. Cycling in mid-state-of-charge would have best longevity.
100% DoD ~300 / 600
80% DoD ~400 / 900
60% DoD ~600 / 1,500
40% DoD ~1,500 / 3,000
20% DoD ~1,500 / 9,000
10% DoD ~10,000 / 15,000
But it's recently been discovered (no, sorry, that link I don't have) that charging to 90% is better for longer life than charging to 100%.

You mentioned keeping between 40% and 90%, which is a 50% DOD. I think charging to less than 90% is much better so 70% -> 20% (or even 50% - > 0%) is much better than 90% -> 40%. Basically, what kills the battery is how full it is when you stop charging it.
I charge my phone up to about 70% unless I know I'm going to need the extra capacity.

I bought a Pixel 2 (non XL) 2 days ago, went straight for the March update and have only installed limited amount of apps. 25% brightness and 4G disabled (only using 3g) and no bluetooth.
Day 1: 100% charge overnight 68% battery left at around 17:00
Day 2 100% charge overnight 73% battery left right now Screen usage since full charge: 1h 31m
Does this seem normal? I was a bit surprised that I "only" had 68% left after the first day since I barely used the phone.
Or should I just let it calibrate and not think about it for a few days?

Make a factory reset and wait 3 days to see if there are any changes. I usually lose around 3-4% overnight which sound reasonable.

This is a "Quick guide" to your battery - APPLIES TO Li-ion BATTERIES ONLY! (simplified version of an older thread http://forum.xda-developers.com/showthread.php?p=3834773#post3834773 )

Charging tips
partial-discharge cycles can greatly increase cycle life, and charging to less than 100% capacity can increase battery life even further
after a full charge, a Li-ion battery will typically lose about 5% capacity in the first 24 hours, then approximately 3% per month because of self-discharge and an additional 3% per month if the battery pack has pack-protection circuitry
no need to charge for 5+ hours for the first time (priming), this doesn't work for li-ion chemistry
use ONLY ORIGINAL or HTC CERTIFIED chargers and batteries (they have extremely important function of cutting off
the current when charging is at 100% * )
battery cannot be reconditioned by over-charging - avoid higher than 4,2V current (which might boost capacity but shorten cycle life)
no need to worry about memory effect with "unscheduled" charging
avoid soft reseting your phone while charging
allow several full charges after doing hard reset to get accurate reading
try to keep battery stress as low as possible when charging (sure shot is to charge the phone when turned off)
a deliberate full discharge and recharge every 30 charges corrects "wrong reading" phenomena in most cases, if ignored, the battery gauge will become increasingly less accurate
using battery chargers that feature a reduced float voltage (4-4.1V) can increase battery life when used to charge a 4.2V Li-ion battery
Discharging tips
full discharge cycles (down to 2.5 V or 3 V, depending on chemistry) should be avoided if possible (except for above mentioned case of recalibrating device)
using only 20% or 30% of the battery capacity before recharging will extend cycle life considerably. As a general rule, 5 to 10 shallow discharge cycles are equal to one full discharge cycle
avoid frequent full discharges, very deep discharges will quickly, permanently damage a Li-ion battery
avoid high-stress discharging, slower discharge=better battery life
discharge level doubles with every 10°C (18°F) of increased enviromental temperature
Usage tips
avoid extreme load conditions (applications using a lot of energy)
avoid keeping a fully charged battery at high temperatures
battery stored for a year or more will start "aging" - irreversible
capacity lowering
maintaining a Li-ion battery in a fully charged condition will shorten its lifetime
store batteries charged at 40%
replace battery if original level drops bellow 80%, battery will lose about 10% of useful capacity each year (whether used or not)
* Selecting a charger that uses minimum charge-current termination (C/10 or C/x) can also extend battery life by not charging to 100% capacity. For example, ending a charge cycle when the current drops to C/5 is similar to reducing the float voltage to 4.1 V (see fig.3 bellow). In both instances, the battery is only charged to approximately 85% of capacity, which is an important factor in battery life. The letter “C” is a battery term used to indicate the battery manufacturers stated battery discharge capacity, measured in milliamp-hours. For example, a 2000-mAhr rated battery can supply a 2000-mA load for one hour before the cell voltage drops to its zero-capacity voltage.

Thank you for a very informative post. Very good info here.
How can I full discharge my battery? Simply left my TP on until it dies? I am wondering that if it is wrong reading battery level, maybe it switch itself off when it reads 0% but maybe the real battery level is..10% or 15%, how can I be sure that the battery is full discharge? My TP is 3 month old, so, or my battery is damaged, or my TP is not accurate reading battery level; I was forgotting that sometimes I have done some soft reset while charging (but not in the past two weeks)

Noticed something interesting the other day, here are the series of events that occurred:
- Battery died - phone turned off (is that considered a full discharge?)
- plugged it in, and it started to charge. The lights on the pad began to pulsate.
- Sometime later I realized that the phone was off so I turned it on. Mind you the lights were still pulsating indicating that it was charging. After the Version # screen came up and just before the Windows Mobile screen comes up. The lights which was in the middle of a pulse, stopped, and began again from the start. Is that considered an interruption in charging?
This should be a sticky!
The main problem I've come across is an inaccurate battery meter. Quite a few people using RRE WM6.5 have reported battery issues, but I've noticed its the meter, not the actual battery.
I RARELY did a full discharge (and I've had my phone since it came out in November). So after flashing the ROM, I did a full discharge. It stayed on 20% for a long time, then it stayed at 7% for a long time, then it seemed like it was at 1% forever. The phone finally shut off. I did a full charge while the phone was off. Now the battery meter is MUCH more accurate.
I'm using RRE's and noticed the "meter" issue. Think I'll give your suggestion a try and let it die over the weekend and juice it back up.

My phone has been off the charger for about 8.5 hours now. I sent/received about 10 texts, and I've had about 10 emails pushed through Windows Live and my battery is at 92% now. All on Edge with a good signal. Not too bad for me.
Feedback
I just would like to ecourage people to leave their feedback, if they tried some of the tips from this thred. Just to see if they are relevant in "real" life.
THANK YOU ALL!!!!
Battery Life
While the Fuze doesn't get the greatest battery life, one thing I immediately noticed was the extension of life when I switched my email from checking every five minutes to once every hour.
Just saying.

Every 5 minutes would cause a huge drain in battery. You would be better off pushing email to your phone than checking every 5 minutes. Once per hour isn't too bad unless you're getting lots of emails every hour.
This is great information...thanks for the tips...and yes, getting emails every five minutes SERIOUSLY drains the battery...i learned that the hard way

I noticed when I could watch my battery drain and the phone was burning hot.
It was also shocking when it had 100% charge when I went to bed and was dead when I woke up.
Same here
MX, I thought I was going mad (going m-m-m-m-mad, I say). Last night, I turned off S2U2 (a notable battery drainer) and my Pro was at 100% battery at around 11pm, woke at 7am to find that the battery was @ 5%! To my knowledge, nothing else was running - certainly no phonecalls or texts and no other actions. Only thing I noticed (because I had forgotten) was that the Bluetooth headset was still connected and switched on - surely this couldn't have killed the battery in 8 hours?
i get horrible battery life and i follow all of the "rules" is it really possible that active sync is the battery killer ?
I heve recently bought a new HTC Touch Pro. After just few weeks, battery's gone crazy. It doesn't want to recharge, even connected to charger for 16 hrs. I got the icon of charging, I can still do anything as usual despite the battery doesn't save any energy. Could it be some energy drain? I'd be grateful for help.
gmanfuzing: I think it depends on how much operational memory does the ActiveSync use. Try shutting it down.
edit: problem solved, gentlemen. It's a failure of my ac adapter. Sorry for making trouble.
There seems to be a bunch of battery questions around again so........bump.
my battery has gone to hell
im on sheps 6.5 with the newest att radio
i had my phone at 100 pct an hour and half ago and it has since dropped to 85 and ive sent literally one text
Battery Drain Problem - Day 1
I got my Raphael 5 days back and immediately installed few apps and did some tweaks (energy and performance) using PHM Reg, Diamond Config tools and suddenly the battery started draining like crazy. ( 45% ) in 4 hrs.
I did a hard reset, disabled TF3D, did some energy saving tweaks using Advanced Config.
Here are my readings...
8.30 am - 100%
9.30 am - 98% - 2% Just Standby ( No push mails or Data Connections )
10.30 am - 95% - 20 mins MP3 and 2 SMS
11.30 am - 90% - Did Absolutely Nothing except 4 checking the battery
12.30 pm - 90% - Did Absolutely Nothing except 4 checking the battery
1.30 pm - 86% - Disabled Battery Icon ( Soft Reset ) Installed Ariel Battery
and continuing I'll keep updating...
BTW is this reading normal??? Personally im not too pleased.
P.S.: Just want to know how can I know what version of ROM and Radio is currently there in my device

Few days ago I received an extended battery for the Note 4 from MPJ.
The size of the battery is x2.5-x3 bigger than the original Samsung one.
It holds up to 6440mah and the packages comes with an extra back cover for your Note 4.
As we can see from the picture above the design is user friendly and the colours match exactly as they should match. Overall the design is not boring and it is eye catching.
Now the back cover has a gloss finish and it is also thicker and taller so the battery can fit correctly.
It does add an extra bulk to your device but from my perspective I don’t think it’s that much noticeable. Note 4 is already a big phone adding some extra height won’t be a problem, but yes it doesn’t look as good as with the original back cover. I had zero problems in everyday use with that back cover, not even with pockets.
Now let’s start talking about the battery life and how it performs!
Day 1 :
The battery life was just how I expected! As we saw earlier the battery has 6440mah which means 2x3220mah which is the capacity of your Note 4 original battery. With the OEM battery you can get 6 hours of Screen On Time (SOT) in 16-18 hours of total use. With this extended battery I managed to get 12 hours of SOT from the very first day! How awesome is that ? The pictures below talk by them selves.
Day 2 :
I have charged my phone through the AC. The battery life was awful! Only 7:30 hours of SOT, which can be achieved from the original battery also. I think my AC in that specific room is a little bit faulty that’s why the battery drained out so quickly.
GameBench :
I ran also GameBench to test out how many hours the battery can hold up playing Traffic Racer. I have played for 15 minutes and i lost 3% of battery juice. GameBench claims that the phone can last 6.5 hours playing this game from a full charge.
Day 3 :
I have recharged the battery from 7% to 100% from a power bank and I am at 62% at the moment with 4 hours of SOT and 10 hours of total use. That means the battery is doing better than Day 2.
In total i got 11 hours of SOT and 1 day and 4 hours of total use, which is great! I managed to get 2days with a single charge check out the screenshots below
The battery charges quite fast, i managed to charge it from 8% to 100% in 2 hours and 5 minutes.
Conclusion :
Pros :
- Battery performs great, it can last 2 days with medium to heavy use and can reach up to 12 hours of SOT
- In very light use it can last up to 3 days. (It drains 2% every 8 hours on idle with WiFi on)
- Full Idle can last up to 5 days (I believe even more)
- Beautiful Design and Colors match perfectly
- Feels great in the hand
- The extra bulk is NOT a problem
- You can buy it either with NFC or without
- The cutouts for the speaker,S Pen, Camera are perfectly aligned in the correct position
- It does add some kind of protection
Cons :
- The back cover has a gloss finish, it would be much better if it had a leather texture like the Original Cover
- Charging on AC is very slow compared to Power Bank
- The battery without the back cover can fell off , its not tight enough.
Overall its a great battery, having 12 hours of SOT is amazing.
The extra bulk was no problem for me instead the phone is heavier and it feels more solid.
I recommend this battery to everyone that uses their Note 4 heavily. People who think that 6 hours of SOT is not enough should get this battery.The only downside is the back cover, I wish it could have a more premium feel although I will continue to use this battery on daily basis
You can buy your own MPJ extended battery from here :
http://www.mpjbattery.com/mpj-6440m...10r4-n910t-n910a-n910v-n910p-eb-bn910bbe.html
NOTE : When restarting the phone you get some extra juice between (10-30%) , that happens because the phone can read up to 3220mah and it gets confused with that extra battery power.
great review... I have no experience with extended battery but maybe i am going to try

I do appreciate your review but that particular statement is not true at all because when you run the battery sensor display codes display stats and battery tests results are clearly denoted in voltage which is the key component in determining the battery life in percentage, not just in phones but world wide industrial and domestic battery applications. There's no way it reads in mAh. I studied battery technologies and applications in campus and in all our test runs about batteries the voltage was the key component in determining battery % never the mAh capacity which also varies infinitely because of the apparent resistance the circuit in it will give. Therefore you cannot use a infinitely varying component to determine a definite component.. NOT POSSIBLE! Voltage is still used to date in all battery run applications as the key determining factor in battery life. Just study how the intelligent battery charger works and you will see it clearly for yourself, that in the note 4 the 9v fast charge is actually the bulk phase in charging the battery, then comes the absorption stage and finally float which both require the 5v charge to complete these two processes that follow. So effectively not requiring the 9v all the way through and dropping to the regular 5v which effectively charges the battery very very well to within 90-95% of it's theoretical capacity. There's no way the phone reads in mAh because the A in mAh is totally load dependent as I have pointed it out previously.
The process you are observing there is taking place exclusively in the battery and is designated as the Redox reaction that when a battery suddenly is unloaded with a load requiring a significant current to run, the process of providing electrons still continues but because it doesn't discharge through the load (as it has been removed), electrons now build up at the cathode so that when the phone now turns ON, it finds a higher potential difference between the anode and the cathode which in turn the phone reads as a higher voltage hence translates that to higher % battery life.
Proof: leave any set of discharged batteries lying around for a while then come later and measure their voltage, tell me whether the voltage that you left them with is the same as it reads now. That is proof of the Redox reaction in ALL batteries.

I read your review and it looks quite interesting. I have tried many "fake" extended batteries, are sure this is the one ?
Do they ship fast in Athens ?

I do appreciate your review but that particular statement is not true at all because when you run the battery sensor display codes display stats and battery tests results are clearly denoted in voltage which is the key component in determining the battery life in percentage, not just in phones but world wide industrial and domestic battery applications. There's no way it reads in mAh. I studied battery technologies and applications in campus and in all our test runs about batteries the voltage was the key component in determining battery % never the mAh capacity which also varies infinitely because of the apparent resistance the circuit in it will give. Therefore you cannot use a infinitely varying component to determine a definite component.. NOT POSSIBLE! Voltage is still used to date in all battery run applications as the key determining factor in battery life. Just study how the intelligent battery charger works and you will see it clearly for yourself, that in the note 4 the 9v fast charge is actually the bulk phase in charging the battery, then comes the absorption stage and finally float which both require the 5v charge to complete these two processes that follow.

Not entirely true. While not all devices will use current sensing for measuring consumption of power, voltage alone is not an accurate reading of a lithium battery's state of charge. The discharge curve between 3.7V nominal and 3.4 is the bulk of the battery's capacity. Yes it may be 4.2V at full charge, but as soon as you put a load that will quickly drop to 4V, even 3.9V depending on screen brightness or total current draw (heavy CPU activity, etc). It will then remain at that nominal voltage level (roughly 3.7V) through 60% or more of the battery's capacity. Voltage drop under load can be used, but you still need to know what that load is. If I have read correctly, phones that do not have current sensing capabilities have a "table" that outlines what parameters will equate to what mA current draw. IE: 75% screen brightness with 20% CPU load is about equal to 450mA current draw (pulling those figures out of my a** here, not factual)
I couldn't find the exact picture I was looking for, but here is an example of lithium based batteries' discharge graphs. Granted these are under constant load scenarios, but the point is made. Voltage alone is not an accurate reading of a lithium (whatever, ion, FE, cobalt, etc) battery. I know these aren't lithium ion batteries so the voltage levels are different, but the graph looks very similar, just different voltages. Again all these graphs are all under a constant load scenario, something our phones do NOT have the privelage of doing. Current load is always changing, from screen brightness, cellular/GPS radios, CPU/GPU activity, etc.
The Redox reaction is only applicable in a no load scenario. Discharge a 1S 1000mah battery at 1 Amp for 30 minutes. Let's assume everything is perfect, you will have consumed 500mah of power, and voltage will probably be about 3.5V under load, and 3.7 under rest. Let it sit (at the same temperature it was under load, say 35C), and come back a little later. Yes voltage may have climbed to 3.8V but as soon as you put a load it will quickly drop.
I'm not fully educated on how phones determine state of charge, but I'm guessing it is more software based on a combination of voltage level, and ASSUMED current draw based on those "tables" I mentioned above. Some phones do actually have current sensing built in. I think some of my older HTC phones would actually give you mA current draw, and could log mAH consumption.
"Smart charging" or whatever you want to call it is merely limiting current once cell voltage reaches 4.2V. This is why the last 20% of a charge takes longer than the first 80%. If voltage rises, current drops. Don't see the correlation to that in terms of measuring a discharge capacity.
Temperature also plays a large role in a lithium's voltage level. I'm an avid R/C guy, flying helicopters mainly. We use large 6 Cell 5000mah lithium polymer batteries with 35C discharge capabilities. If you were to charge your battery in the garage in the winter, and the cells were all balanced at 4.2V per cell after charging. You bring that battery inside to a toasty house that voltge could climb to 4.25 or 4.3/cell. Not a good thing but it allowed you to squeeze a little more capacity into your battery for that extra 10 seconds of flying. Granted our motors are pulling upwards of 10Kw (yes, 10,000 watts or more) so I'm sure it was negligible, but still it made you feel like you were getting more. Getting off topic here, sorry.

Problems can occur with some cell chemistries however, particularly Lithium which exhibits only a very small change in voltage over most of the charge/discharge cycle. The following graph shows the discharge curve for a high capacity Lithium-ion cell. This is ideal for the battery application in that the cell voltage does not fall appreciably as the cell is discharged, but for the same reason, the actual cell voltage is not a good measure of the SOC of the cell.

Was there any documentation with the battery that stated whether or not you could use fast charging with this battery? I'm assuming since you said it charged in a little over 2 hours that you kept fast charging enabled.
I'm looking for an extend battery, the zero lemon is just too big for me so I like this one better.
Only downside is not being able to find a diztronic style "case" for it any longer. Just a slim rubber case similar to the diztronic that I love so much.

Received my MPJ Battery today, unfortunately the case doesn't close on all 4 sides. No matter how I do it, either the left side or the right side won't snap shut. Hopefully the replacement works better. Can't wait to see how much SOT I can get though. Had an extended battery with my Note 2 and loved it.

You have a good expo because as you say not all phones use precise mechanisms to determine battery charge but for a flagship model like the Note 4 we can't afford that kind of mediocrity. I was only addressing the part where the battery seems to acquire charge after a reboot which temporalily actually occurs due to the temp no load situation.
After reading all of the comments i decided and ordered the battery. Can anyone inform me, when the battery arrives, do i use it until it drains and charge for 8-10 hours ? or do i put on charge immediately and after 8-10 hours use it ?

I also ordered this battery after reading this review because my note4 had an insane battery loss about 20% in 1 hours!!!
I got this phone in January 2018. So, at this point it is almost 3 years old (just over 2 years and 9 months) and the battery life is pretty appalling now. I get perhaps half a day with a full charge. The main issue seems to be turning on WiFi/Data. As long as the WiFi is off which is usually in the night, the battery drain is relatively minimal. But the moment I turn WiFi on in the morning, the battery drains like crazy regardless of what I do with it. I usually just let it sit on my desk doing mostly nothing. I stay at home 24x7 nowadays due to the Covid-19 lockdown, and work from home. So no poor or uneven network signal. In terms of regular usage, it is a few minor phone calls via WiFi mostly, and a bit of solitaire games for an hour or so.
Take a look at the screenshots of the battery drain and life. Is there something I can do to enhance the battery life of this? Make it drain less with WiFi?

There is also a battery replacement service here in London for a reasonable £60. I am wondering if I should do that or simply buy a new phone as this phone has anyway reached the end of life software support.
If it was me, I would be getting a new phone. Almost 3 years old. Time for a change. I've got the 4XL, but you could easily move to the new 4a, or 5 series. Good luck with your decision.
Sent from my Pixel 4 XL using Tapatalk
Sadly I am just not impressed with the new Pixels. The idea of having a weaker, less power hungry CPU and a bigger battery is nice, but the price is just unreasonably high. I wish it was cheaper especially given the competition. I have been searching for my perfect next phone and I think I should switch to something new soon as well. My top priority now is a decent price and a great battery.
The new P5 has a 4080ma LiPo battery. Haven't read much about the difference between LiOn and LiPo batteries. Not easy finding the perfect phone. Best of luck.
Sent from my Pixel 4 XL using Tapatalk
Here is a nice comparison between Li-ion and Li-Po batteries: https://www.androidauthority.com/lithium-ion-vs-lithium-polymer-whats-the-difference-27608/
Seems like Li-Po has low self discharge so it will hold a charge longer. But also has shorter life span, so I am guessing fewer charge cycles than even the current batteries. Interesting but unfortunate drawbacks. Oh, I wish for the day when we make a true battery breakthrough and have batteries with insane charge density in tiny packages and great life spans! Some day!
If I were you, I would get a battery replacement. No need to upgrade, especially when the price for the new pixel 5 is exceedingly high and disproportionate. I would then install a custom ROM so that you can get the latest security updates. That's what I'm going to do, I will wait for the next Pixel generation. If it's not any better, I may hold out longer. This is a fantastic phone that works ridiculously well despite the years, and we should avoid falling into needless consumerism. Just my two cents...
Enviado desde mi Pixel 2 mediante Tapatalk
I am considering that as well. I am not thrilled by the options I have at the moment. I like that the Pixel 2 is nice and small and it works well for my everyday use except the battery. And the battery is also not a big concern at the moment as I am mostly at home and can keep it charged regularly. And if I go out, I always take my battery pack with me to top up the phone if it goes too low. I am thinking I will continue with this for more time and even avoid a battery replacement, which will save me money and avoid any potential damage to the phone due to a poor job of replacing the battery.
What Android are you running, 11? Mine had horrible battery life, like 50% in 15 minutes because of an issue with a radio app on my phone
I am on Android 11. I just uninstalled a bunch of apps and the idle drain with WiFi on has reduced significantly. I will check how the battery life is now.
By chance, is your wifi and bluetooth scanning enabled in Location? That scanning can drain the battery.
Sent from my Pixel 4 XL using Tapatalk
WiFi scanning was on but not bluetooth. I will continue to track the battery life.
I got my Pixel 2 in November of 2017; I haven't noticed a significant decline in battery life, although it does seem that Android 11 is a lot more battery hungry, especially on standby.
This might be due to Android 11. The battery life is horrible. I also thought the same thing, bought a new battery and turns out it's a software issue.
Update: So I did end up putting in a new battery for my Pixel 2. It cost me £60 to do so here in London via iSmash, the official authorized repair partner. Given the retail price of the battery is around £10, the labour cost was £50 which is worth it as I would have damaged the phone if I tried it myself (I nearly did that with an old Droid many years ago).
So I got it repaired on 1 Dec. I have been testing the battery for a week and I do feel that the battery life has improved. I now have to charge only once a day or so after moderate use, kind of like what it was at the start. I do feel that perhaps the Android 11 update is still causing more drain than normal however, but still better than before.
I am using the AccuBattery app and before replacing the battery, the app approximated my battery health at around 1800-1900mAh compared to the design capacity of 2700mAh. Now, it is approximating it at around 2600mAh if I consider the latest charge cycle from 14% to 100% (+86% took about 2251mAh). So I am guessing that the battery replacement was well done and successful. I am also able to make my phone last longer even without turning on battery saver all the time. However, there is still some idle drain when I don't do much but have WiFi/data turned on. I am attaching screenshots. I wonder if this is software issue due to the latest Android 11.
So now, I have 2 questions:
Is there a better app than AccuBattery to get a sense of battery life/capacity? AccuBattery takes many charge cycles to get to a decent estimate.
Is there sometime I can do regarding the battery drain due to the latest Android 11 update? I believe lot of people have raised this complaint and I too noticed an increase in battery drain after the Android 11 update, despite the aging battery. And I seem to notice the same drain with the new battery now.

Also, that is pretty amazing! You used your phone for 3 years and still did not notice significant decline in battery life!? Do you charge more carefully, such as only charge to 80% or 90% and not let it drain below 30-40% or something to extend the lifespan of the battery? Also, do you use the phone very sparingly, or is it not your daily driver? Do let us know what you do and how you managed to take care of the phone so well it lasted this long. That would be very useful information!
Meh I wouldn't have updated it.
Scope storage sucks.
If it's an LI:
Limit charges to 80% or at least stop at 90%
Don't regularly discharge below 20%
Li's like small frequent midrange charge cycles; 40-65% is ideal.
Avoid high temps especially with a fully charged cell; high cell voltage and high temperature degrade the cells much more rapidly.
Never charge a cold battery; 72-90°F is best.

Sorry for the late answer.
I am a heavy user, when I'm at work I generally have my phone on the charger. I plug it in all night too. Standby battery life is pretty good; Android 11 does seem to be more battery hungry, so if I don't use my phone at all, I might get 30 ish hours of life. But, with realistic use, it will probably last me around 8 hours, with the amount of video streaming I do.
I have never paid attention to charge cycles. Phone software handles that, and you'll find that most li-ion battery management only charges to about 80% of chemical capacity to extend the life of the battery. Tesla battery packs will last up to 500,000 miles, because the management software limits the usable charge to about 40% of the cells' actual capacity. Phone software does a similar thing, where 0% is actually about 40% of the battery's capacity, and 100% is actually about 80%. Your phone lives its whole life in that 40% of usable capacity. Maintaining a state of charge higher than 80%, or discharging below 40%, shortens battery life.
I'm not going to pretend that my battery still performs like new, and I wouldn't easily be able to determine that anyway - with the age of the battery and the software updates, it will never be the same as it was.
If I don't **** off at work, or I am not antisocial when we go over to friends' houses, it'll last quite a while, but given my heavy use I tend to keep it on a charger anyway.

Don't have to worry about this. Firmware and software manages battery state of charge. Use it normally.
Also, the "proper" temperature for a lithium battery is between 40 and 80 degrees F. They will retain a better charge at room temperature because low temperature increases internal resistance, but you are not likely to damage anything. Charging, or maintaining a high state of charge at temperatures above 90 degrees shorten the life of the battery.

While you can use LI cells in low temps without harming them, charging them at low temps Li plating can occur which will permanently degrade them. The temp I saw stated was >80F.
Others stated standard temp for charging/testing Li's for longevity was a temp of 72F; I wouldn't go much below that when starting a charge.
&
Somewhere below 50-65F Samsung fast charging will revert to slow charging to protect the cell.
You won't find that in literature but you can observe it.

I am not sure the software on our phones does anything quite as aggressive as you are suggesting, i.e. charge only till 80% and let you use it only till 40% of the physical capacity. Given the rated capacity of the internal batteries in phones, which can be easily identified via a teardown and how much charge is actually done based on measurements, unless the phone has a setting (some phones nowadays allow you to set an upper limit to the amount of charging to 80% or 90%) most phones including the Pixel 2 do NOT do any such kind of battery management. The Pixel 2 does let you charge till 100% of the battery's actual capacity and let's you drain it pretty much completely as well. So I am not sure what info made you believe that it does such battery management.
Tesla's etc. I can believe do such battery management as it is crucial for the longevity of a very expensive car.
I just got a warning from my relatively new (10 day old phone) that it was closing down applications due to a battery temperature of 62.4C and a CPU tempereature of 59C is this normal?
I am not 100% sure which one it was complaining about, I believe the battery temp

144°F is hot for a cell phone battery, although technically it's close to some Li's max operating temperature range.
Shutdown temperature on Samsung phones for the battery is around 108F. I don't go over 103F battery temp and typically go screen off at a battery temperature 101F.
The cpu can run hotter.
Is the processor running a high load?
If so the big question is what's ramping up the cpu cycle usage? Find the problem app(s) and sort out the problem.
It sucking up internet bandwidth? Bloatware?
What's using the most battery?
Try in safe mode.
You're burning up the battery longevity. Limit the top charge to 80% for now until you resolve this issue. Keep screen brightness at 50% or lower.
Running at or near shutdown temperatures can cause permanent damage. It's especially hard on a fully charged Li battery.
Edit, you posted while I was replying. You may have knock some life out of the battery. I had one over temperature event on a fully charged Note 10+ battery that caused it to lose about 5% of its capacity. It failed a little more then a year latter.
3 things Li's don't like; full charges, high temperatures and charging below 72F.
Never attempt to charge if below 40F.
I agree. The only damage will be to the battery. The phone itself can withstand well over 100c without problems. The internals can take soldering which is 300c ish. The battery however, not too fond of anything above room temp.
at least a one off, won't sit it up there again!
Also seems to have been lucky it does not seem to have had aany affect

Edit, you posted while I was replying. You may have knock some life out of the battery. I had one over temperature event on a fully charged Note 10+ battery that caused it to lose about 5% of its capacity. It failed a little more then a year latter.
3 things Li's don't like; full charges, high temperatures and charging below 72F.
Never attempt to charge if below 40F.

Ah that is fien I only use C
I wonder if the phone will even tell me if it has lost capacity .... it seemed to charge to 100% this morning, but im not sure if that is 100% of what remains or 100% of its undamanged sate

The Fahrenheit system is better suited for everyday life. It uses whole numbers in the temperature ranges most used real life.
Lol, walking a klick is easier than a mile, mph is faster, and a °C is a lot hotter than a degree in F.
Consider your cpu heatsink broke in and well seated
You will see lost capacity as a decrease of SOT.
The % indicator doesn't see capacity per se but voltage level only.
Keep an eye open for cover bulging; any battery swelling is a failure.
Watch for shifts in charging time and erratic fast charging. As a battery degrades or fails these change, it can be slow or overnight.
After seeing one failure on my heavily used device I decided to just change out the battery every year or so. It's not worth destroying the display over or deal with the loss in capacity. Most batteries aren't that hard to replace once you know how. In a few phones though it's not pretty. The Note 10+ is rated as hard but in reality it's not if done correctly... so actually watch one being replaced in person if possible.

*mumbles kelvin*
I am not sure I will be able to actually see battery swell ... the front of the case is glass, the back is metal and its IP 68 ...
I bet there is an app for actual battery condition out there though!
There certainly is for laptops etc, SOT? something of time .... my guess is surcharge over time?

It will either push up the display or rear cover. I missed that early warning on my Note 10+ because of the case, oops. I was very lucky it didn't damage the display.
When the battery reaches 80% of what its new capacity was, it's reached the end of its useful service life and is considered degraded. Degraded Li's are much more likely to fail. If it shorts internally it can make a hot mess of the phone. Degraded cells are more likely to form dendrites that puncture the anode/cathode insulation and cause a short. Cold charging can cause Li plating which permanently damages the cell capacity... avoid charging under 72F, although a minimum of 82F is a preferable start charge temperature
Accubattery's charge/discharge logging feature is very useful as is the handy battery temp reading. I firewall block it though.
Screen On Time, I use to find misbehaving apps and gauge the battery over time. My typical usage is 7-13%@hr. 7-8% browser, 10-12% watching vids.
hmmm a 15 minute charge put it at 87% charged

I go by % per minute. On the N10+ when fast charging between 30-70% it runs at 2%@min.
On a bad battery it increases to 3%@min, or fast charging will fail to engage in spite of meeting % and temperature range requirements.
A failing battery will charge too quickly and/or erratically.
Accubattery makes it easy to overview the behavior.

What do you mean? It lost calibration or capacity?

It is meant to carry a Li-Po 4500 mAh, non-removable battery, the current rated charge at 100% is 1017mAh

Where is that coming from?
What's your typical SOT?
Every battery is losing capacity over the time, nobody can hinder this. But this can get slowed down if discharging / charging the battery is correctly done.
To those that have use the phone for a year what is your battery health percentage without battery protection and with battery protection, im just trying to see if using the battery protection is worth it or not
There is no question concerning battery protection, if you use a device with a lithium ion battery and only use it between 30 and 80 % this will greatly extend the useful life of the battery. Using a smartplug and software to control the charger plugged into it, I have a five year old Pixel phone with a battery health percengage above 85% that’s still working fine.
I only wish that Samsung’s battery protection option was 80% instead of 85%, which would better enhance battery life.
Almost a year with the phone (10 months), always used the battery protection. Stock One UI 5.1, Snapdragon version.

1. Never used battery protection feature because I always charge my phone to 100% and keep it connected for another 5 minutes or so.
2. I don't use Adaptive Battery feature either because I haven't seen any benefits from it.
3. Lots of theories on keeping the phone battery between some range. I don't follow it because benefits from such practices are insignificant during the expected ownership life of the phone (about 5 years on average).
I turned off battery protection 1 year ago and never looked back. Today, at 100% charge it says I have 1d19h of charge remaining. I charge my phone to 100% every night while I sleep. I see no difference in my battery performance at all.

As I previously stated, self implemented battery protection on several phones I have owned made a huge difference for me. Charging to 100% every night left me with a very noticeable decrease in battery capacity within a year and a half or so. Maintaining the battery between 30 - 80% produces a night and day difference in battery endurance. I still own a Pixel 2XL that has never been charged to 100% and the battery capacity is around 85% and the phone still works great.
According to Accu Battery my S22U was at 99% after 1 year of charging to 85%. I never used wireless fast charging and kept the charge between 35 - 85%.
Everyone has an opinion on this. I have no problem getting 2 days of use charging to 85% so why charge to 100%.

You can set battery protect to turn on at whatever battery percentage utilizing Samsung Routine. I did this for a while at 90%, but have since turned it off as I will most likely upgrade my phone by next year.
I use battery protection overnight and whenever I need my phone connected. Ex: Android Auto.

How big of a difference are we talking here, before i use my S22U i have an Oppo F9 which still have good battery despite charging it too 100% every day for 3 years but that's probably because the SoC isn't very strong to begin with so it doesnt use that much power, while my phone before that which is an iphone 6 that is a hand me down and collectively used for 4 years have really bad battery where i have to charge 2-3 times despite only using it for messaging and youtube
the reason i really care about the battery health on this phone is because of how expensive this phone is compared to the other phone i have in the past and i do plan to use it for a long time

In the past I have had a Sony Z2 and a Nexus 6P both suffer drastic battery degradation in under two years by fully charging them every night. With my next phone, a Pixel 2XL, I started using a smart plug which I configured to be controlled by software monitoring the battery charge and turning off the battery charger when charging reached 80%. After five years, this phone is still operational and its battery health is above 80%. I am now using similar technology on my S23U.

Been Warp Charging my OnePlus 8T at full speed for 2.5 years now, often charging it twice a day. Battery life is fantastic and so is it's health. Practical experience taught me that some of the theories may be true, but have little practical application. One must NOT bother too much with these things as they ruin user experience.

Could you share a link of the smart plug you're using?
I've never used Battery Protect. I charge my phone over night to 100%. I use wireless charging almost exclusively. By the time I leave work, it is at around 78%. I have it set to best performance.
I've taken it on the road several times and always had enough juice to make it to my hotel after 10 hours of traveling.
I haven't noticed any battery degradation.
