Anyone know where to get an extended battery? Thanks.
I can't even find a place to buy a regular battery for the phone. I'm not sure if I would need one, but it would be nice to have. I'm in the habit of charging it the last hour I am at work so no matter what, I'll never run out of battery even if I go somewhere straight from work, but a spare battery is always a good thing to have.
I have a wild guess as to why not.
I noticed this phone battery has the "near field communication" labeling on the BATTERY. The other phone that I'm aware of having NFC, (the galaxy s2) does NOT have this wording on the battery.
Why did I notice this? I randomly read that there is an SD card manufacturer that is putting NFC chip's into their microSD cards, and even some ipod cases are getting NFC chips built into them as well.
I don't know too much about NFC, but with the labeling being on our battery, and not the S2, I kinda think our NFC chip is actually in the battery, and not the phone itself. If an NFC chip can be put into an SD card or case on a phone that never had NFC to begin with, I don't see why it couldn't be put into a battery, especially since one of the terminals might not even be for power, but just for an NFC connection.
That's my theory, I could be wrong!
you're probably right. This is how it is with the Galaxy Nexus, also built by Samsung. I hadn't noticed the label, but I also wasn't looking for it.
I'd be curious to find out what an "extended battery" for this phone would look like. I'd be all for it so long as it kept NFC and didn't bulge out of the back
I'd be interested to find one. Being on a stock rom and standard battery, my battery drops about 5% in five mins just checking Facebook. GPS drains it another percent per min it is in use. Half way thru the day my battery is dead. It really sucks having to carry around a charger. I'm also using juice defender and other tweaks I know to save battery
I'd bet you a waffle cone your screen brightness is set too high.
Forget most of those "battery defender" apps, especially if they are those stupid task killing applications.....a program being in active memory is not necessarily actually doing anything, which means it is not using your battery, and if it gets killed, if the OS needs it open for any reason, it having to be re-opened will just use cpu cycles anyway
I'd agree with most people that using the automatic brightness option is very annoying, it's really sensitive and it also tends to make the screen not be bright enough. Having said that, using any of the many available brightness widgets can be a very good thing.
The stock one is not so bad, personally I've been enjoying powerful control, http://goo.gl/2vZXl but I've had great battery life and easy readability if I use the brightness setting where it looks like a half moon.
If you're outdoors in the bright sun, you'll need the screen to be as bright as possible if you want to read it, but otherwise it's fine. The screen brightness is always the single biggest battery usage factor.
Personally I've always disabled the haptic feedback as I think it's annoying and I'm sure that using vibrating alerts is also a huge battery drain.

My screen brightness is at zero without automatic brightness on, and im not using haptic feedback. The phone battery is fine if its just sitting over night, but as soon as I turn on GPS to use maps for 5 mins or to check facebook the battery just drops a % every min. So i guess the phone is fine if Im not using it, but then whats the point?
You're exaggerating.
I've never had a phone battery drop 1% per minute.
Look man, I just spent 5 minutes playing music at max volume, while getting directions to 8 different places in google maps, sent two emails, downloaded a new app from the market, and received one text message.
Battery level after all this? Still at 100%. Does that mean I can do this an unlimited number of times? No, it does not.
Frankly, I don't believe you. I've used this phone, and my previous phone for playing movies at full screen brightness with the audio being played through bluetooth to my stereo headsets. Does it effect the battery status? You bet it does.
Two weeks ago when I last played a snes game on my phone I did so at full screen brightness over bluetooth to a ps3 controller. When I wasn't playing the game I was sending or receiving text messages and had vibrate on. I played super metroid from the very beginning to almost through the end of the game. When I play snes games on my phone I tend to use quick save and quick load and frame skipping very commonly, effectively letting me do things "perfectly" but this is a lot of saving and loading and running the game even faster than how it normally is. I started at 2, and the next thing I knew it was 6:00 and I was supposed to meet a friend for dinner at 6:30.
But for crying out loud you are saying you can drain your battery from 100% to zero in less than 2 hours.
I'm calling shenanigans. I don't think you could even do that intentionally, unless you sat there and forced the phone to vibrate the entire time.
Phone batteries don't last for days like they used to. Batteries have not changed too much in the last few years, but the things phones do, and the screens they do them on certainly has. Stop expecting your phone to last over the entire weekend even when you actually use it.

Something to keep in mind:
When this phone hits 100%, it STOPS CHARGING. Even plugged in, it will no longer be drawing power into your battery, yet it'll still be running on battery.
If you plug it in when you go to sleep, it finishes charging within 2 hours, then it goes 6 hours idling on battery power but it still says 100% until you disconnect it. Then, while you're using the phone it'll adjust as you use it until it gets to the right level. This is likely what you're seeing.
If I use my phone from the moment it finishes upping to 100%, I get great battery life. I get great battery life in general and have been happy with the phone.
Of course, this might be a totally different issue where you just got a bum battery. But it's something worth considering.

I don't believe this is true. I hate to constantly be a naysayer in this thread, but this didn't seem logical to me so when my battery went to full, (when the battery is full, unplug charger text showed in the notification bar) I kept it plugged in and set it to play a couple tv episodes on full brightness while I did laundry and made dinner.
Two hours later, I first looked at the battery status while the phone was still plugged in. As expected, it was at 100%.
I unplugged the charger, waited a couple minutes, and checked again.
Still at 100%, which completely makes sense because I've never had a phone that behaved as you've described.
I also would have noticed the battery dying very early, *every single day* because my habit for the last week or so has been to plug the phone in when I go to sleep. I have an app called syncme that pulls files off my computer such as music and video while I'm sleeping, and on average it transfers about 6 gigs of data this way, every single day.
I don't know if you've ever transferred 6 gigs of data on a phone via wifi, but yes, it's not exactly battery power friendly.
My phone's always been 100% battery when I leave for work, just like my last phone was where I also plugged it in at night.
Just saying!

Actually he is pretty close to the way it operates. The way your phone gauges battery life is similar to your car with gas. When the meter reads 100%, it is really more like 98%. When the battery reaches true 100%, the phone will stop charging the battery (but will run off of USB power, not the battery). They do this to account for small variations in the many variables that affect a battery's performance (like temperature). Likewise, your phone will read 0% before the battery is truly completely drained (this is also to protect the battery - they don't like being charged to 100%, nor drained to 0%).
This could also greatly affect your previous test on battery performance. To get a more accurate result, let the phone drain to about 60%, then test the time to drop a percentage point.
What you are talking about is a suggestion that the battery meter doesn't necessarily update it's strength meter all of the time, and you even say that the phone runs off the plugged in power at this point.....

Before you discredit anyones post, you should understand how many battery chargers work, and the importance of them shutting off following a complete charge. Here is a quote regarding Li-ion battery maintenance :
Li-ion cannot absorb overcharge, and when fully charged the charge current must be cut off. A continuous trickle charge would cause plating of metallic lithium, and this could compromise safety. To minimize stress, keep the lithium-ion battery at the 4.20V/cell peak voltage as short a time as possible."
Many chargers have this feature built in to avoid any overheating and/or damage to the cell. I'm not saying this is the case because I have not tested whether the battery charging circuit in this particular phone, or it's charger operate, but I will say that this has been the case in MANY of it predecessors.
That being said, I think an extended battery would be a welcome addition to the options of this phone. Mine too only lasts a day at it's best. Perhaps not 1% a minute...but then again who knows?
Since I'm outside a lot all day, auto brightness was killing my battery by constantly cranking up the brightness. I've since lowered it to about 30%, and surprisingly it's still bright enough out side at that level, and I'm at 30 minutes screen time with 90% battery left, which translates to about 5 hours screen time until it's dead.
So for those having battery issues, try this out. Even if you aren't outside a lot, I still think autobrightness kills the battery since it's constantly using sensors to find out what lighting condition you are in.
The auto brightness is too aggressive.. the screen is much brighter than it needs to be for given conditions.
I also always wondered why auto brightness sensors are on the front, because it doesnt make sense. If the sensor is on the front, it sees YOUR background.. if it was on the back, then it would see the actual background that you would be looking at the phone on.
Agree. It consumes noticably more battery with auto brightness. I also noticed that i can have brightness at full blast and get amazing battery compared to auto brightness on and compared to my previous phones in general

Same here I work in an outside environment and the screen is vibrant enough for me to see even when the screen is at 40-50%. In fact I turned off auto brightness the very first day I got the phone because it did seem to be a bit too aggressive.

1 hr 35 mins screen time and at 70%.
It was definitely the auto brightness eating my battery previously.
Hi,
I have the s2 classic and I love it. I have read on CNET that they were able to get nearly 3 days of battery life before charging. I can't get 24hrs of usage before charging. I have changed the brightness to 5 (the screen does shut off and is not on the always on mode), I shut off wifi and NFC . I am not using it all that much, what is everyone else getting on average? I just want to know if I might have a lemon.
Thanks

Hey @APT-ART , You can't try to turn off the automatic heart sensor for longer work on battery. Also the black background (pure black, so pixel are not lighted at all for that part of the face) will help to improve it.
For me it depends on how many notifications there are during the day, what applications I am using and how I charged it last time (I recommend to clean both the back part of the watch and the wireless charger as well). Also for some faces the brightness level of 2 or 3 should be enough to use it as a normal watch WiFi on but NFC off, also the automatic heart sensor turned on but less regular setting.
The battery stands for me for about 30 - 40 hours. But for the first two times I've got only about 16-18. Just let it discharged to 0%, then charge it to 100% without turning on. Good luck!
I keep my brightness at 3, keep always on watch face turned on, tilt to wake off, heart rate off, wifi on, nfc off, S voice watch face listening off, get probably 50 notifications per day and after a 16 to 18 hour day have about 40 to 50% battery left.
I think S Voice watch face listening, higher brightness, and tilt to wake (especially at a higher brightness) does the most damage to battery life.

Really good tip, I am going to let the watch discharge to 0% and see what happens. thanks! :good:
With very light usage I can easily get 3+ days. I turned off nfc and WiFi. I left on the heart rate scanning. I use it as a stand alone watch at work since I can't use my phone. I have the brightness at 3 and ambient display off / tilt to wake on. Not ideal usage for some, but it's a good setup for me.

I'm assuming everyone here has the non 4g version and that's why you guys are getting pretty good battery life. Got my S2 yesterday with 4g and fully charged overnight. Took off charger and about 8 hours later the S2 is at 38%. Not happy but going to try that discharge tip. To see if it helps. Also may have to tweak some other settings. I had the Gear S 4g and it didn't drain that much. I can usually get a days worth out of it.
you need several cycles to really know what kind of battery life you can expect; one days worth wont tell you a thing

You can change it by going into the s health settings on the watch. Options for auto heart rate are frequent, moderate, or off. These settings are separate from if you actually go in and start and exercise. I have my auto turned off (to conserve battery) but when I go in and actually start an exercise session on the watch, it will monitor heart rate. The auto heartrate is just for random monitoring throughout the day....having it set to off will not impact monitoring when you start an exercise.
As we all know android head unit is slow to boot when it is shutdown (cold boot). But is reasonably fast when it is just waking up from sleep (ignition turned off less than a set time and turned back on).
So, I was wondering if anyone tried keeping head unit from going complete shutdown and keep in sleep mode while ignition is off.
How much current draw did it have in sleep mode? Any negative effect?
It would be the best if I head measured current draw before hooking up the radio, but I did not think about that at the time. I don't want to cut the wire again if I don't have to (meaning someone else has measured already. )
I didn't measure it myself but yesterday I read a post regarding the power consumption while on, sleeping and off. It was 1.2A (~14-15W) while sleeping which is ****ing ridiculous imho but could be the explanation why there isn't an option to keep the device sleeping longer than 2 hours. Given that consumption while sleeping, your battery would be probably dead in less than 3 days of standby time.

Attribute that to "made in china". With just a little bit more thought, they could have designed the MCU board to shut down completely while putting the CPU into deep sleep, and end up with a sleep/standby mode that consumes negligible power.
I.e., it shouldn't use any more power than a half-decent TABLET does in sleep mode with the wifi turned off. My Nexus 9 will standby for a couple of MONTHS like that, and its battery is a very small fraction of a car battery.

I did measure the power consumption in sleep mode before I installed my Joying in my car.

That sounds more reasonable, although that still a bit high for leaving car parked for few days.
Extending shutoff time to 24 hours maybe ok. Don't know how yet, but it should be possible.

I wouldn't feel comfortable with a sleep time of 24h+. Lets say its 400mA and you use your car on a daily basis. Thats 24h*400mA = 9.6Ah. I am not an expert when it comes to car batteries but I read somewhere that if the battery capacity drops lower than 50 or 60% the starter has a hard time, especially with the colder temperatures ahead (at least here). And you have to consider that the older the battery the less capacity. I wouldn't test it out myself but I would be very interested in someone doing it nonetheless

500mA is a little high to left in that state for a long period of time. 500mA is the current that drain one car lamp of 5W, like the ones on the rear, the tiny ones on the front, or the ones used in the passenger compartment. With a good battery there should be no problem for letting it in that state for a day or so, but for an old battery this could dry your battery in a few hours.
However, i agree with the fact that the time for going to shutdown should be user selectable.
i was thinking of the same thing, now i am completely ignorant of the electornics side of it, but isnt this something the devs here can take on to fix from the software side of things, i.e keeping only the CPU in deepsleep and shutting everything else down?
It's necessary to keep in mind that these HUs are not like tablets. These HUs has more electronic inside of them: MCU, sound ampliffier and, surely, some more electronics. All of them drain current, and not all of them are capable of getting in a low power mode like CPUs do.

Hi! I think I've found the solution!
In my HU, Erisin 3015V, I go to settings and just below "GPS" option, there is another option that says "Extension configuration" (Or something like this, just because my unit is in what chinese people think is spanish...) and into this option there are three ones, the first of them says something like "Delay when acc is shutdown", and this option has several values. The first time was selected 30seconds, and the HU Always made a cold boot. Then I adjusted it to the max, 2 hours, and now the unit has warm booted after more than 1 hour of beeing slept.
Try you and update, please... I think that 2 hours is enough for most situations.
in which way is this a solution?
2 hours is the current maximum for all headunits I know and it is not a secret or hidden option, but this thread is about keeping the unit in sleep mode for a longer period of time than the 2 hours. (no offense)
Oh! Ok. Sorry. I was mistaken
prolly not much of a problem for me in. 08 duramax with dual deep cycle batteries.
on another thought, you people with standard cars with standard starting batteries... you COULD install a second battery. a deep cycle battery. run HU off it. isolate it from charging system while vehicle is off. automatically reconnect to charging system with a relay of some sort when vehicle is on. this way you NEVER stand the chance to drain your starting battery. and as its a deep cycle, draining it down empty doesnt damage it unlike starting batteries. i wouldnt even worry about it anyway because it would prolly take like 12 months to drain a decent deep cycle down. lol

whats the math behind this calculation?
12 months = 365 days = 8,760 hours
8,760h x 0.4A (consumption of the head unit while in sleep mode) = 3,504 Ah
Show me that car battery and I will give you a cookie
Thought of the second battery myself. In general, I think thats a viable option but there are some downsides as well. The generator has to be very powerful to load two batteries at once or you even have to add additional relays to prioritize the main/starter battery. Of course that problem depends on wether your primary trip range is short or long. This should work if you are driving on a daily basis or at least every second day for 30-40 minutes I guess.
Lets say you install a deep cycle battery with 80Ah and it is fully charged, the theoretical standby time is a bit more than a week (ofc that could be enough for some people):
80Ah / 0.4A = 200h = 8.3 days (just the theory)
As I dont know much about deep cycle batteries I will cite from wikipedia:
A deep-cycle battery is designed to discharge between 45% and 75% of its capacity, depending on the manufacturer and the construction of the battery. Although these batteries can be cycled down to 20% charge, the best lifespan vs cost method is to keep the average cycle at about 45% discharge
Click to expand...

Long story short, you wont get 8.3 days from a 80Ah deep cycle battery. If you are fine with the reduced life span, its around 160 hours (6.6 days) and if you follow the manufacturers recommendation you will probably get around 4-5 days.
I am not trying to work against you here, but I dont know if thats really worth the trouble (costs & installation). Thank you for your input anyway.
Hmm. My truck runs dual AC Delco 48PG's. It appears each are 70 amp hour.
Here's a couple other options that come to mind.
1. Most viable and affordable in my opinion. Wire up an easy attach Battery Tender. I have this set up on my motorcycle. When I roll in to the garage after a ride, I mismount, attach battery tender, and my small motorcycle battery receives a small trickle charge until next time I ride. Also, do Not use the cheap battery chargers. Spend the extra 10 bucks and get a smart charger. This thing works awesome! I pull all my batteries from vehicles not used during winter and bring them in to the house and have BT on them. If your unfamiliar with these, definitely check it out.
2. Perhaps some sort of small and efficient solar panel that can not only keep up with HU discharge, but enough to also overcome parasitic waste from all other systems as well? Not sure if this is viable. I don't know anything about solar panels. Just throwing it out there
The only issue I have with the battery tender option is... what happens when the user forgets to unplug it before driving off? Other than that it's not a bad idea. There definitely needs to be some thought put into low power modes. I used to hotwire my HU's so that I didn't have to listen to the key-minder on my older vehicles. Difference is that those non-advanced HU's had a real "off" mode even with the ACC wire hot all the time.
The solar panel option would work well for those that park outside and have decent sunlight during the day.
Hi Sorry for my english.
I have a problem.
My head unit often doesn't shutdown after suspend mode.
Maybe 50â„… times works correctly.
Another 50â„… i switch off engine, radio goes in suspend mode ( Black screen and not respond pressing button) but if i switch on engine after the suspend time ( i set 30second but it is so also 20 minutes) the head unit is already on homescreen without reload the s.o.

I have always charged my phones to 100%, this 85% thing is very new to me.
I've never heard about it before until I saw it in my S22 ULTRA.
What are the benefits of charging only to 85%? Does it last as much as with 100%?
Does it really recommended to charge it up to 85%? Im not an heavy user, but also I'm not changing my phone once a year, I'm changing it one time in 3-4 years.
Also, I tried to never charge my phone at night, and trying to catch the battery not lower than 10-15 percent to charge.
So basically, it bothers me a little bit in the eye to see that the phone is only about 85%, because that way basically the battery will run out much faster(significantly, yesterday 10% went down in 45 minutes, which means I'll lose 45 minutes from battery usage for nothing).
So, my question is, is it really worth it? Is there a significant difference between the two options? I'd love your help, thank you all!
The 85% is to protect and prolong the battery life. I agree that you will loose 15% of battery time if not charging to 100%. I charge to 100% and when battery is 10 - 15 I charge to full. I guess on the long run it's better for the battery to only charge to 85%, but I change phones every year or 2, so I'm not to worried about prolonging the battery life
Set low limit at 30-40%
Top limit of 72-85% is better.

Start charge temperature is important to prevent Li plating. Battery should be at least at 72F, 82-90F is better. Cool if charging temperature goes above 99F. Never charge in direct sunlight.
Never attempt to charge at 40F or lower
Avoid having the screen on while changing.
When using, turn phone off if battery temperature reaches 100F or cool it.
Replacing the battery isn't a big deal unless you don't do it on a timely basis. When an Li has reached 80% of it's original capacity it's reached the end of it's useful service life and is degraded.
Degraded Li's are more likely to fail which can heavily damage the phone. Any swelling is a failure replace immediately.
High voltage , temperature and current drain stress the battery. Other than avoiding low temperature charging and going to either low/high extreme voltage ranges constantly I wouldn't worry about it too much.
I now replace my heavily used Note 10+ battery every year or so to avoid another failure, routine maintenance. Batteries are cheap and relatively easy to replace.

So, I understand that it recommended to charge up to 85%? :-D
I searched on google to buy a S22 ultra battery that will keep in home until I need it, but couldn't find one.

I have always charged my phones to 100%, this 85% thing is very new to me.
I've never heard about it before until I saw it in my S22 ULTRA.
What are the benefits of charging only to 85%? Does it last as much as with 100%?
Does it really recommended to charge it up to 85%? Im not an heavy user, but also I'm not changing my phone once a year, I'm changing it one time in 3-4 years.
Also, I tried to never charge my phone at night, and trying to catch the battery not lower than 10-15 percent to charge.
So basically, it bothers me a little bit in the eye to see that the phone is only about 85%, because that way basically the battery will run out much faster(significantly, yesterday 10% went down in 45 minutes, which means I'll lose 45 minutes from battery usage for nothing).
So, my question is, is it really worth it? Is there a significant difference between the two options? I'd love your help, thank you all!

If you can last to bedtime on an 85% charge then fine use that setting if you intend to keep the device for 3 years or longer.
If (like me) you need 100% charge to get through the day, continue charging to 100% and dont worry.
I have been using mobile phones for 25 years and I charge overnight as I sleep. I have NEVER had a battery failure or problems.
Life is short, enjoy your new phone
P.S. If you are worried about stressing the battery by charging to 100%, I suggest you also disable Fast-Charging as that is WORSE for a battery cell than 100% vs 85% iMHO.
I used to charge my Note 10+ to 100%, every day plug it while in my car or plug it to my laptop now and then. After 2 years of use battery health was 89%.
On my Lenovo laptop I stop charging at 60% as suggested by Lenovo vantage. Bull****. Battery lasts a lot less after one year. Almost the half.
Enjoy your gadgets and mobiles. Anyway after 2 years most of us get a new one.

how does one set low limit?
i have a smart plug i use for my charger, only on long enough to charge phone from 20% to 85% (battery setting limit enabled).
i usually charge at 30% to 85%.

I just do it by eye. It's not rocket science.
Accubattery lets you set an alarm if you want.

Keeping a spare isn't a good plan as Li's start to degrade as soon as assembled. So after a year or more of sitting there it will have lost some of its initial capacity.
They should became easier in the future.
Any solution to modify the protect level?
"protect battery level 90%, 95% mod instead of 85%"
85% seem to be very short time of using
For anybody wanting to change the limit from 85% to lets say 90%, you can use the App called Galaxy Max Hz, you can find it on this forum : https://forum.xda-developers.com/t/...ods-qs-tiles-tasker-support-and-more.4404929/
One of the options is to change the battery charge limit, on the lock screen it will still say : "Charging stopped at 85%" even though the battery is at 90% as set in Galaxy Max Hz

85% is actually rather on the high side. Either correct the excessive battery drain or replace the battery. When an Li reaches 80% of its original capacity it's reached the end of its usable service life. It's degraded at that point. Degraded Li's are much more likely to fail. Any battery swelling is a failure.

Actually, the protection level should be 80% or less to maximize the battery’s useful life.

I use the 60% protection on my Lenovo as they suggested and gess what, after 8 years my battery still works fine, and lasts for 2h/3h. I used my laptop every workday on heavy use, and it's the most cheap line, it cost me 300€ in 2015 (Lenovo G50-30 Celeron N2840). It's all day pluged, but when i need to use on battery it's fine!
So i realy think this battery protection works, and my S22 Ultra it's for last at least 5 years, and the 85% it's enough to run my workday.

Maybe. Depends on usage. On my N10+ which is heavily used with frequent charge cycling from 40-60% to 72 to 85% most times I get about 2 years out of a battery. Higher battery temperature shortens the lifespan as well. Fast charging is more stressful as is using the device right after a fast charge. High current drain while in use is also stressful; optimize the device to increase SOT and battery lifespan.
Frequent partial charge power cycling can extent the typical 200 full charge cycles to 800 or more. A partial charge is not a full charge cycle.
Start charge temperature matters.
It's an electrochemical reaction, heat is required for it to charge properly!
-//-
Never attempt to charge if near freezing
Fast charging will not engage if battery temperature is below about 55F to protect the battery.
Charging below 72F or above 103F can cause Li plating which will permanently degrade the cell.
Optimum start temperature is 82-90F, cutoff is 100-102F max. Cool if needed.
Regardless of service time replace the Li when it reaches 80% of its original capacity. At 80% it's reached the end of its service life and is considered degraded. Degraded Li's are more likely to fail
Any swelling is a failure and it can destroy the device. Battery replacement isn't hard or expensive. Just part of routine maintenance...

Here is a good article why it's recommended to not load the batt to 100%
How to maximize battery life: Charging habits and other tips
If you've ever wondered what the best way to charge your battery is, here are some scientifically proven tips for maximizing battery life.
www.androidauthority.com
Personally i just keep the load between 65% and around 20-30%. Only if i know that i will leave the house longer than 4 hours I do a 85% load or 100% if i want to film and take photos. But this rarely happens.
