It has been quite interesting to watch all those threads for the above topic which of course lead to nowhere so far.
I would not exclude myself of the dispute, however we need to think of the issue in a practical methodology and thus conclude what the facts would lead to.
There has been many complaints and unhappy people about the battery life in Touch Pro and many other models. Just a simple question I ask; What would be an acceptable avarage battery life with one full charge? I am sure responses will vary coz there is no standard expectation nor a universal benchmark for this issue!
Whatever the vendor guarantees as an operating expectency measured in hours, is more or less what you gonna get although many wont accept it, but this is it, you gotta live with it!
There are 1000s of users with 10000s of applications and conditions that have high expectations, but they all get even results, so why complain?
What I am trying to highlight is if many have expressed their dissatisfaction of the battery life, I just say; who's right & who's not? Do we all expect to have the same results? My device may run for 3 days with one charge and couple of calls throughout, others may have tougher uses and expect a battery to last for 7 days in a row with just one single charge?
Just think about it and have a collective understanding.

ya made a wise statement here.....couldn't agree more ...
yep, 2nd that
a wm device drains a lot more battery than other phones because it does sooo much more. and its not device specific either
maybe if someone creat app to change CPU to 200- 300 and so on if don`t used for heavy apps will incress battery life. In the PSP there is app like this ans when I used it only for play music set procesor to 100 Mhz
I have had the phone for a week now. I like it. I like how pretty much everything works. I don't see much of any problem but the battery life. Why didn't they put a larger battery in. My Mogul has a 1650 in it. Yesterday morning the phone had a complete charge. I went to worship and used it very little in the morning. By noon time where I showed the phone off to a friend who is thinking of getting one, the phone charge was down below 50%. It should have been 70 or 80% and no less, IMHO.
I've posted this link before on a different section.
http://www.hardwarezone.com.au/reviews/view.php?id=2726&cid=24&pg=6
I get nearly 4 hours as well if I use mine full on. Tried watching a full length movie and my battery meter shows ~50% afterwards.
I thought OP might be interested in seeing this review.
I don't think it's really an issue of someone being right or wrong. I think 24 hours is just a particular limit for cellphones, and once it dips below that we start to worry about the next time we'll be near a power plug. After all, these are devices that we use on a daily basis.
If the batteries lasted 2-3 days, then it wouldn't be a big deal if we forgot to charge once in a while (late night, canceled flight, forgot charger, etc). But as it is, people are having trouble pushing it past 24 hours even under modrate usage, which means if they miss even one charge cycle, they're dead in the water the next day.
Of course usage is a different issue; but if you start modifying your usage habits in an effort to prolong battery life, that's still the same problem. You could turn off 3G, stop mail checking, always close background apps, etc; but without any of those features you might as well use a regular dumbphone -- no point in getting a device like the Touch Pro in the first place.
Last week we went on a short holiday. Both my girlfriend and I have a TP running RomeOS v1.13. She has a GSM prepaid card and I have a GSM/3G/H card.
Her battery lasted 4 working days occasionally calling home to check on the kids and sending a few SMS messages.
I used my phone to check email and LIVE messenger. My battery lasted no more than 20 hours.
So if you by a full featured phone, just to use it as a basic phone you won't complain that much I think. If like me you want to use a full set of features pffffffff... And if you don't mind I would like to keep it at that
My first serious WM phone (I don't count the ridiculous HP 6315) was the Samsung i730. I am a very heavy user and I got used to charging it in he car & carrying a spare battery in my pocket. If it made it to 6PM without going dead I was happy.
The Touch Pro has the same screaming 528 mhz processor speed, plus a vga screen. If it makes it to the end of the day, then I'll be more than happy (haven't received mine yet, it's in the mail). There's always a trade off for speed and resolution. I'd rather carry an extra battery than have a frustratingly slow processor.
I've had my TP for a week now and with a pretty heavy usage, my messenger is almost always on, some internet browsing and a little bit of monkey island on scummvm, my battery lasts 2 days. I can live with that.

Which Messenger are you using? I'm trying to find a good Google Talk client that won't drain my battery.
The battery should be expected to last a day. Past that, would be nice, but I do not feel it is necessary...
If the phone won't even last me a day (and "a day" for me is 14-16 hours at school and work) then it really isn't going to work for me. I hate trying to search for 5-10 minutes to have the phone plugged in during the middle of the day to try to extend the battery to make it just past that 12 hour mark for me.
The CDMA Touch Pro doesn't seem to do too well. Sitting idle, it had about 40% battery after 14 hours, but then dropped extremely quickly after that... I must have sent 10-12 texts and was in a call for about 10 minutes the entire day, no programs running in the background, only the cell radio turned on.

I agree with you 100% - except here is the problem: the vendor guarantees (well, doesn't "guarantee", but no vendor really "guarantees") a battery life that is absolutely not right.
On the Touch Pro, Sprint says the phone has a standby of 406 hours - that's 16 days! Incredibly misleading, and in my estimation definitely not accurate. That's the biggest problem I have with the whole battery issue.
Also, in comparison, my Mogul was suppose to have 340 hours of standby and 30% less talk time - but my Mogul lasted a LOT longer than this phone. I could talk, surf, play games, and have it still last longer than this phone. That doesn't make any sense.

Alright, alright, alright! Let's not mention the biggest and silliest gimmick PPC vendors made us believe in specially those of high-end CPU ones
I might have been worng in choosing "guarantee", but who says! When you read "Stand-by" I am sure that the vendor wouldn't in gods name mean "with any GSM/CDMA network"! I mean just think about't!! Why in heavens name would they shoot themselves in the foot by committing such a thing
I could defy anyone who would tell me that "Stand by" is a standard by itself! Haven't you read "The above are subject to network and phone usage" in phone specs?
In addition to the above, network signal strength matters and is very fundemental to extend/shorten battery life too!
Whether or not the battery was of 1300mAh or 1600mAh, it is all the CPU power management and I am pretty sure that Qualcomm is unlike the Intel XScale as the olden memories remind me of
Like most of you rightly said; change your habit and the battery life will change accordingly.
Just a last lil thought, why isn't there a quick options made available in the market for a higher amperage batteries? If one would care about the total gram units, then I recommend to live with the supplied battery.
Let's all cherish the memory of the HTC Universal, that baby was a hot long-lusty orgasmic son of gun device ever was.
I feel the term "standby time" has been used loosely, never in working with wireless phones have I found a machine that is capable of being on this long without being charged. Notice the "up to" that is always there on these kinds of stats too. What does up to mean? Probably something to do with turning off all the radios so the phone can't actually do anything, it might as well be off.
No matter what you do, computers require a lot of power to maintain themselves in any sort of "on" state. If there are any background processes happening (i.e. cellular radio sniffing for incoming calls and sms) you are really only burning power at a rate less than that of radios + screen.
Phones consume more power than phones did even a few years ago, hell they consume a lot more. Does anyone remember first-gen digital phones? 2 hours battery life, talk/standby, didn't make a difference. In fact the batteries used in mobile phones have changed (lion/nicad etc) probably a lot less than the manufacturers' ability to use less power to get the job done.
You can always strap on a bigger battery, but then you have a bigger phone, making it even HEAVIER!
Ultimately, as others have posted before me, that when you buy a touch pro, it is because you are looking for all the functionality that the machine entails. If you use all of the functions at the same time you are burning the candle at both ends. We buy a phone with a gps, bluetooth, wifi, 3g, vga screen qwerty, 3.2mp camera, etc because we need (or want) all of these features at the same time. When you are using the gps while having bluetooth on visible, screen full bright, wifi still on and music playing, don't be surprised your battery won't get you through the day.
I think that the general consensus here is that typically we should be able to get about 1 day out of the pro. Any more, we are lucky, any less, you either have a defective unit or you may have unrealistic expectations of the device.
That being said, after a few weeks go by and you find yourself actually being able to put the damn phone down for a while, battery life will seem longer too
My experience:
I've come from an XScale phone, which runs Linux and doesn't have 10% of what Pro does (like GPS, wifi, 3G, SDHC support, VGA screen, G sensor, light sensor, etc.) and even without all that it doesn't have a great battery life. I had to recharge it everyday sometimes, because I had pretty heavy use (especially A2DP audio).
With the Pro I can do that and much more and still get at least a full day of battery, which for me is good enough.
Tell me one device that has the same size does everything the Pro does with better battery life.
Unfortunately we are still to see better batteries, which I've read a lot about, especially that nanowire technology which supposedly makes them 10x better, but until then there isn't much we can do. So I don't think it's fair to blame a manufacturer, HTC or not, for poor battery life, because IMHO they did an impressive job on making such a small device with so much power, and still manage a full day of moderate use.
I find that TF3D is a real power hog too. Although I really like the interface, I am trying a run with SPB Mobile Shell instead
It is 3:30PM EST now, I unplugged the phone after a solid charge at 8PM, immediately changing to SPBMS.
It is now about 20 hours later and I have 63% remaining, that is a 37% discharge. I have been using the phone normally for the purpose of this experiment and normally the phone would be at about 30% remaining with tf3d.
There is a thread about this here
http://forum.xda-developers.com/showthread.php?t=441767
Hi All,
I'm wondering if besides the GPS, WiFi, 3G and Bluetooth.... the application processor, running at 528MHZ is not a cause for this poor battery life time?
Adrian
The reasons why we read many different opinions is that people use phones in very different ways. I can usually cope with the short battery life but sometimes it is really annoying. It just needs a few hours in a bad coverage area and the battery drains completely. Or an unexpected need for TomTom to make the battery go flat before I get back home in the evening. I used an HTC P3600 (which is a very similar phone from a featureset point of view) for two years and I never had to worry not to listen to music at the airport or on a plane because I wouldn't be able to use the phone after landing. Instead I have had this problem already twice with the Pro... this terrible battery life is really spoiling my user experience with this phone.

Well, as I said in my previous post, discounting the hardware keyboard and the fact that it wasn't a very attractive phone my old HTC P3600 used to do exactly the same things with a much longer battery life.
Hi
Have had this phone for just a day.
Been struggling to make up my mind whether I want to get it because of the limited memory.
But finally decided to go ahead because it has good reviews on its performance and battery life.
No complain about the performance, but the battery life?....
Played Tripple Town for just about one hour and 30 mins and the battery goes down from 66% to 35%, the majority of which is comsumed by the screen.
So here is where I am. 5 h 47 m on batter, 32% left, 69% of the power drain is because of the god damned screen.
Seriously HTC, how can you manage to get so screwed up with such a decent processor.
you get rid of the removable battery, ok, nowadays the battery lasts reasonably long.
you get rid of the Micro SD card and force us to use the rubbish dropbox. 50GB 1 Yr cost $99. Why don't spend that money to get us a decent bigger memory? But ok I want the performance, I am willing to give up a bit of space for that.
But Finally SUPER AMOLED. Seriously, what kind of dump decision is this to fit a more-than-a-year old technology to such a decent new processor?? when we know all the bad thing about this screen.
It alone kills all the power efficiency the 28nm processor can offer us.
So now this phone's battery cannot out perform (when you are actually using it) neither of my previous phones: Dell Streak and Atrix. Don't tell me I have to compare the battery life by switching off the screen and just let them sit there.
I am very disappointed. very disappointed.
This will be the last phone I buy from HTC.
It sounds like you don't know about how to manage phones.
You prob was running lots of applications at once and brightness all the way up it still won't go from 66% to 35% sounds like a bad unit you have.
no... the brightness is at it's lowest level.
I use anrdoid assistant to kill process once an hour.
There is very unlikely this is a bad unit. Nowadays these manufacturers control the production quality very good that the chance I get a bad unit is probably as low as winning some lotto.
For starters, your device is BRAND NEW so battery will take about a week or so to break it in, just be patient. Also, killing tasks will only end up using more resources since Android will most likely just start them back up once it gets the chance. Run your battery down the first couple of days and charge it overnight and you will start to notice it getting much better.

Kill Process runs only once an hour. So during the time I was playing, it probably just ran once. I doubt it will cost much power at all.
I understand it needs time for the battery to warm up. But even with that taken into account. it is not looking good. It reminds me the suffer that Desire caused my friend.
Hopefully this doesn't turn into a bigger issue; keep us posted!

sorry mate but this is just stupid. first of all the battery meter is not calibrated in a new phone meaning the reported battery state is not accurate. you have at least to charge the phone once to 100% and discharge it fully to calibrate the 2 extrem states. before that everything displayed is just a rough approximation. at the first discharge i had ~20% left and the phone was down to 0 in just some minutes of heavy use. after 2 cycles i get ~-10% for an hour of heavy use. so stop crying and give the phone some day's to adjust

Well I hope jodue is right: the battery needs time to fix itself.
I will give it a week to see whether things will improve. If not I will go to store to get a new one.
I have been using Android Assistant for my Streak and Atrix. It turned out to be just alright.
Anyway I will remove it and see how it goes.
Ppl have wrong idea that AMOLED is more power efficient. I remember reading a review some time ago on battery life of smart phones. It tested a number of phones and the outcome is that actually on average the AMOLED (at that time there wasn't SUPER AMOLED yet) devices last less than others.
But anyway...

This is the most stupid thing one can do. The processes will likely be restarted by the OS and you consume more power than you would have consumed by letting android do his things as designed.
Google itself suggests not to do it. Even the most honest task manager apps suggest not to do it. (e.g., http://android.nextapp.com/site/systempanel/doc/autokill ).
Anyway, before judging battery life wait few days. I own a One X, and battery life improved suddenly after few recharging cycles. ;-)
About the display. I readed somewhere in this or X forum, that:
1. LCD does consume less power, but for X version, since its bigger screen, it takes more
2. AMOLED screen power consume depends on what it have to display (colors). Black/dark colors need less power to be shown while white takes the most power...
You get 25GB free on dropbox with all one series phones plus a further 25 per referal

This. Many people don't know/forget about this. Using a dark theme on apps you use most on an AMOLED phone can save a lot of juice, much more than all those stupid Juice Defender/task killer/manager apps can ever hope to.

You cannot ask all the website to go dark background can you?
Ppl use the phone to do different things. Games, Browing internet... thats the whole point, the phone should perform consistantly for all tasks, not just looking at dark home screen. HTC hasn't even figure this out yet??

no battery issues here
No battery issues, with slightly higher than average use (downloading loads of apps, playing some games, using google maps and a half hour driving nav and some music lsitening) over the first few days I've averaged 24-36 hours which I'm pretty happy with.
There are a few software things I don't like though
First, I miss having settings in the notification tray, it's one less tap of the screen. Also, the tweaked recent apps list seems pointless, you have to flick from one to another... the Stock android 4 recent apps scroll is much better, it let's you see/do more with less interaction. I also noticed a bug where the wireless signal will appear as null in the notification bar but if you view the the details in settings it says that the wireless signal strength is excellent!
Don't let any of this put you off though it really is a great phone and feels great in the hand... CM9 may rescue all!
Have the One S now, arrived a short while ago. The most annoying thing is that a stock device only has 9GB of that 16GB free when you get it.
This is nuts, I will not be using dropbox, there are many nefarious reasons why HTC want people to use dropbox or any cloud storage, this does not work well while I am roaming folks. This is not good for a business phone, I maybe sticking with my DesireHD.
Its sad, that many ppl who consider themselves technophiles do not even understand the battery of their devices.
ANY device with a modern battery should be initially charged overnight or 7-8hrs at least even of the little green light tells you it is all OK after 4 hrs. Do that, and give it a week to break in and I assume there won't be anything to complain about anymore.
Somy link to a decent site discussing these battery care tips and characteristics should be auto-pinned to each new device subforum cause the first complaints are ALWAYS about the battery life it seems...
I have used this tablet for 2 days now and almost everything works perfect (thanks to latest ota) but there's one thing that is bothering me. Battery life. I had ipad 3 for 2 months but I finally sold it and bought the infinity. Now I know ios sucks on phones AND tablets. But the battery life was amazing. I could use it to browse and for games for 9 hours at least. But on the infinity I am lucky if I get 4 hours browsing. 4 hours sucks on a tablet. But I think that wifi is the problem. I have added 2 pictures were you can see I used the tablet for 1 hour last night then I used it for almost 3 more hours today. Now the battery is at 10%. But I was wondering why the battery uses 62%? On my galaxy nexus wifi is using 5%.
Have I got a faulty unit or is it like this for everyone? If so please let me know fast so I can send it back before it's too late.
Somethings not right there. Tests/reviews done by some major outlets (thinking PC World or Engadget) reported 9 hours of video play over wifi with screen at 50% brightness. iOS has always had good battery life due to their stict contols over the OS, but you should be seeing more then 4 hours. Hell I was at 40% and played WindUp Knight for hours straight last night which takes up much more battery then a movie. I usually don't suggest using task managers, but there is one built in by asus, I'd use it and see if you can kill some processes. Also be mindful which profile is being used. I stick to balanced most of the time and switch to low when the battery starts getting low (24%ish)
http://www.engadget.com/2012/06/25/asus-transformer-pad-infinity-tf700-review/
The TF700 packs a 25Wh battery rated for up to nine and a half hours of runtime. Indeed, it lasted nine hours and 25 in our battery rundown test, which involves looping a video with WiFi on and the brightness fixed at 50 percent.

Thanks for the reply. I am always on Balanced and i am seeing over 20% down in an hour. Maybe i have a faulty unit?

Exactly, it all depends on what your doing OP. The movie scenerio in the review doesnt take much juice in that it uses the low power single core. I don't know for sure, but web browsing may require all 4 cores to kick in depending on exactly what your doing. Regardless, your wifi being a big consumer is easy to deal with. Somewhere in the settings is an option that automatically turns wifi off when screen is off.

Well, all i was doing was using chrome... I think it's pretty bad when i cant browse for more then 4 hours on a tablet. I thought it had to do something with WiFi since its using over 62%. I did the same test with my nexus where i i just used chrome and when i looked in battery , wifi only used 10%. Maybe there is a bug with wifi?
Try Battery HD for some averages/estimates.
I tend to get about 9+ hrs of reading, balanced mode, WiFi off, and about 7 hrs of browsing over WiFi (undocked, dock charges me about 2/3 full), but it all drops down drastically for gaming, which is about 4 hrs you mentioned.
If you get 4 hrs of pure browsing, I'd consider re-flashing, wiping data and - if these don't help - returning your device.
Chief Geek's point has much merit, and you could always look at (for example) GreenPower or some other time-/screen-based toggler. They do pretty well, and you do not even lose out anything except direct push functionality. (Does it really matter for 99.9% of mail when it comes in once every 15 or 30 minutes? When it does (when you're buying a house or something), shut down the toggler for the time being and cope with some battery drain, then when the situation has resolved, enable it again.
And try using BetterBatterStats for your statistics -- the main battery stat app Android offers has some quirks to prevent meaningful interpretations of many scenarios. Let that get a few charging/discharging cycles and then look at the stats.
So battery hd tells me I should get 8 hours of browsing and 9 for video playback. Will do another test tomorrow with screen on whole time and see how long it will last watching videos. Also battery hd tells me I can play 3d games for only 2 hours. Eh

When it does (when you're buying a house or something), shut down the toggler for the time being and cope with some battery drain, then when the situation has resolved, enable it again.
And try using BetterBatterStats for your statistics -- the main battery stat app Android offers has some quirks to prevent meaningful interpretations of many scenarios. Let that get a few charging/discharging cycles and then look at the stats.

So battery hd tells me I should get 8 hours of browsing and 9 for video playback. Will do another test tomorrow with screen on whole time and see how long it will last watching videos. Also battery hd tells me I can play 3d games for only 2 hours. Eh

Remember that these are just averages for your device, at least in the beginning.
If you mistreated your battery upon receiving it, it can kill battery life. You are suppose to plug in your asus tablet for at least 8 hours (well beyond the tablet would say the battery is 100%) the first time you get it. This is sound advice for any new Lithium Ion Battery.
Then you can start using it. Letting the battery die at 0% also decrease the life of the Li-Ion battery every time it happens (ignore old sites that say you should do a full discharge cycle every 2 weeks, that was for old Nickel Cadmium batteries).
Juice Defender is typically a phone app but you can run it as well to detect if any background processes are eating up your battery life.
I get almost 10 hours on my TF700 with moderate usage (mix of browsing, video playback, reading, etc.).

All correct -- there is a lot of disinformation going on with batteries (especially regarding the charging cycles, although a single, long, full charge and then draining to zero charge actually helps calibrate the battery indication algorithms in the device). The optimum minimum charge level seems to be about 40% or so I've read.
Juice Defender and Greenpower toggle WiFi on either time- or location-based profiles, and that works on tablets as well. Recommended!
Your phone doesnt actually discharge a battery to zero. The thing with lithium batteries is they maintain voltage untill nearly the end. This is a very large benifit for modern devices. Once the voltage starts to drop the phones circuitry cuts it off and prevents it from powering on with the LVC circuit that checks the battery before allowing phone to power on then immeditately cuts it (first attempting a power down then all out power cut). This happens to protect the battery. So what the phone considers a dead battery is simply an exhausted battery ready for charge. If a lithium is actually dischardged completely it will damage the cell and prevent it from taking a charge. The power being given to it is then converted to heat. The battery then ignites and very very bad things happen such as your house burning down. The point of all that is to point out that discharging your phone to "zero" isn't actually doing any damage past the normal wear and tear on the battery. I buy batteries that cost hundreds for some of my RC hobbies and have learned the hard way about how lithium batteries work. (bypassed LVC and ruined a $80 3S2P pack)

i have actually read that Li-Ion batteries can be used out of the box. Sp i turned on my infinity right away. I put the charger in, but i still used the tablet. It was about 25% when i got it out of the box. So what you're saying is that i have basically ****ed up the battery? If so, then i will return and get a new one. But i dont understand why most people say that you can usre a device with Li-Ion battery staright out of the box without needing to charge it first.

Nothing to add, technical and extensive, but fully correct, sir. I think we may have had a slight misunderstanding, however: my point was that discharging your phone to 'zero' (and as you rightfully point out, that is not an actual fully discharged battery state) is a required step in calibrating most device's algorithms (some devices, such as my SGS2 do not need this because of advanced hardware). I'd rather not fully discharge any Li-Ion batteries either.

A typical case of RTFM, an affliction I sometimes suffer from as well, as do most men. Hahaha! Do you think ASUS put it in the manual for laughs, or just to give you a few more hours of painful desire to use your device while you cannot, yet? Nah, it's there for a reason. Sometimes, though -- and again that's SGS2 experience -- just running a few battery cycles might make the readout correspond to the actual battery level again. You could at least give it a try, right?

I have used this tablet for 2 days now and almost everything works perfect (thanks to latest ota) but there's one thing that is bothering me. Battery life. I had ipad 3 for 2 months but I finally sold it and bought the infinity. Now I know ios sucks on phones AND tablets. But the battery life was amazing. I could use it to browse and for games for 9 hours at least. But on the infinity I am lucky if I get 4 hours browsing. 4 hours sucks on a tablet. But I think that wifi is the problem. I have added 2 pictures were you can see I used the tablet for 1 hour last night then I used it for almost 3 more hours today. Now the battery is at 10%. But I was wondering why the battery uses 62%? On my galaxy nexus wifi is using 5%.
Have I got a faulty unit or is it like this for everyone? If so please let me know fast so I can send it back before it's too late.

I see the same picture here. Looking at the battery stats I see WIFI using >90% of the battery when surfing in balanced/50% backligt mode.
Hope they fix this.
Hi,
Previously I successfully rooted LS966 and bricked while flashing ROM (Lesson Learnt) and paid a bomb to repair the motherboard.
I now have H955 - 15B. I successfully rooted the phone via online remote connect help, because I felt it would be cheaper than last time. After rooting,
Debloated mostly all google Bloatware and few system apps based on a list from another discussion on XDA,
Installed Pimp My CPU and reduced to 1230 Mhz
Doze to block background data traffic
Greenify to stop background processes.
This has been quite a versatile combination for me and the battery doesn't drop by even 1% until the screen is on.
Once the screen is on I am losing 1% of battery every 3 - 5 mins.
I am getting a Screen On Time of 3Hrs.45Mins only.
I have also read up on Battery Calibration issue and this is my second full charge - full discharge cycle.
But the battery percentages are still going down at the same speed.
My screen is drinking above 50% of my juice at 100% brightness. I tried to change that few times but it is more or less same.
Earlier it used to be around 15 to 30%. I am attaching current consumption picture.
While I am enjoying a good Stand By Time of upto 12 to 14 hrs, my Screen on Time is reduced to 3hrs 45Mins.
Is this normal?
Or I am missing something?
Is it the way ROM was flashed on old built before rooting because of soft brick while rooting?
Any indication will be of immense help. Many
Many Thanks.
Seems the way it should be. Changed my battery almost a week ago and I get maybe close to 4 hours of SOT, depends how you use your phone, I use it at 80% brightness though and standby time while it's just sitting on the table is days. :good: N.B. Using android 6.0.1, although it used to be pretty much the same on 5.1.1, maybe less standby time.
Also I'm pretty sure Pimp My CPU shouldn't be compatible with this phone because of the kernel and lockdowns. Maybe they've found some kind of loophole, doubt it though.
Also for the battery calibration, I fully discharge every month to 0% and then charge it to 100% while not using it and once it hits 100% it's good to go. Just the way I do it, not everyone does it the same.
Also, I never trust remote help of any kind, who knows what crap they might do, and even though I am an amateur at android rooting and flashing, I've done it myself every time cause I don't trust remote stuff.
And depending if you want root or not, you could use android 5.1.1 15c(although I don't know if the difference between 15b and 15c is that big) with root or android 6.0.1 20c without root. It's rather simple to root on 5.1.1 though, so many guides here, as long as you follow them to the letter.
You don't have to agree with what I've written here, it's just my opinion.

Are you sure you get close to 4Hrs of SOT on a brand new battery because I get 3 Hrs and 50 Mins or so but less than 4 Hrs on a phone which is 6 months old. Never changed the battery. If that is the case then I think I am doing alright. I have seen SOT Tests of phones like Pixel and One Plus T.
I dnt think pimp my ROM has any restrictions. It kind of works smoothly. It helps me cool down the hot CPU also. I have ovecome the dreaded overheating issues of G Flex 2 easily with clocking my CPU.
I have done the battery calibration. But it quite didn't help me.
I went paranoid because immediately after the root I started to observe the battery percentage on the top. And I felt its falling drastically. But on the other end my stand by time has gone upto 15 hrs. The battery doesn't drop even by a single percent until the screen is on. Once it is on it goes down drastically.
I think of the battery calibration as kind of a safeguard, it's not a necessity.
The pixel and oneplus are different beasts altogether.
Also, as your phone is only 6 months old then it's battery should be ok and as I stated before battery life depends how one uses their phone, I tend to play a few games here and there with 80% brightness and such so it takes a bit more on my end. I personally haven't seen over 4 hours of SOT with my phone ever since I've had it, but your mileage may vary.
As for the PIMP my CPU, if it works for you good, I personally moved over to 6.0.1. When I was changing my battery I removed the motherboard out of curiosity to see how the thermal pad is and only one edge was touching the frame, so I added some Arctic MX-4 thermal paste between the frame and thermal pad and the temps are surprisingly better now. Still tends to get hotter than it should but throttles a lot less now and the screen brightness doesn't forcibly drop below 80% now, even when gaming. It used to drop to 50% etc before when just browsing the web. Anyways, that's that.
It might be some background stuff eating your battery too if you had better battery life than you do now, or it might be because of the motherboard change. Unfortunately I'm not smart enough to say for sure. Also, the more you look at the battery percentage the worse it looks
Sincerely,
Azure Potato

Pixel is too expensive for me honestly and I am not really into expensive phones like iPhone or Pixel.
I am quite happy with G Flex 2's performance and I was only worried about SOT of 4 Hrs. I re calibrated battery and discharged and charged again 100% Thrice.
Somehow battery last over 15 hours after rooting. For example, its 3PM and I have 70% battery left even with SOT of 90 mins of movie. That is 1Hour30Mins.
And you're right, the more you look at battery. the more complicated it gets :laugh:
After rooting - Greenify + Pimp My ROM + Doze + Uninstall System Apps - combination is giving me 15 hrs of usage per day. It more or less includes phone calls, WiFi browsing, Network Data Browsing, Some videos and crazy amount of Twitter, all put together through out the day.
But I am still interested in SOT per single charge.
Interesting.... Same problem here
I'm on 20A, 6.0.1
You're sitting on about the expected SOT. I get anywhere from 4-5 hours and almost never take my brightness off 0%. I'm running a fully debloated 15c setup, same as yours except a version increment higher. The most intensive thing I do on here is install new apps, no gaming or anything. If you have the Facebook app, try switching to Facebook Lite which you can download off APK Mirror. Does everything the normal app does but without all the bloat, it's only a couple MB. Apart from all the tweaks you've already listed, there's not much else we can do. I've always wondered why screen takes the most battery usage by far, maybe it's just the screen type we have. Screen off is great, I lose less than 3% every night including background updates. Screen drains at about the same rate yours does.
I'm looking for used phone and Pixel 3 seems to tick all the boxes.
I did check the Wikipedia page though, and there's a fairly disturbingly big list of various issues. Is this still relevant these days?
If you mean these issues (https://en.wikipedia.org/wiki/Pixel_3#Issues), I have not encountered any of them. I have a Pixel 3, not the XL version. I have had it for a couple of years, and have been very satisfied with it.
Alright. What about the battery life I keep seeing brough up a lot? I used to have Xperia XZ2 Compact, which has pretty much the same capacity and almost identical display resolution, and I had no problems at all. Not playing games and not watching Youtube either, ever.
I go two days between charges, but I am not a heavy user. No games, nor videos, and not a lot of screen time. I use this app to limit the charge to 80%. https://github.com/sriharshaarangi/BatteryChargeLimit
That is supposed to extend the overall life of the battery. It is usually down to 45% - 50% after two days. I could probably go four days between charges, but draining it too low also reduces battery life.
it's been about 2 years now with my p3 and still I'm not willing to ditch it, it's a great phone. only downside is battery, if only it was bigger.. it would be still the best phone lol, nowadays all phones are just too big... with low usage i can get through the whole day on a single charge though
After a very few months with the phone, I have to say it's pure ****.
The batterybarely lasts one day despite not playing games or watching Youtube.
The phone also randomly restarts and gets stuck in millions of reboot loops.
The camera is ok, but not so awesome everyone says. Maybe if they put real glass over the sensor, I don't know.

Wow, certainly not my experience. After the first couple of updates, I've not had a single issue. I did have an overheating issue the other day using hotspot. For my use, battery lasts for a day, but requires nightly charging.
Agree, my camera definition is "good enough" still not a DSLR replacement.
