Yes, I know. We're all sick of these battery threads. But I just came across something I wanted to share with you all.
Before I continue: I don't use any task killers. And I've read every battery trick thread on here and on Android Forums, so I've done it all. The CDMA fix. Rooting and using OCWidget. Charging it to 100%, turning it off, and then cycling the charge with the phone in the off state. And of course, disabling every data hungry app plus setting screen brightness to 50%. This is my 3rd Android phone, so it's definitely not my first rodeo.
So last night I was using my Evo as it was on the charger. I was browsing the web, and checking out some new apps in the market, so the screen was on for quite a while. I took my Evo off the charger, did some heavy texting, some browsing, Facebook, Twitter, etc, etc, and about 5 hours later I was at 80%. I then put it on the charger, and went to bed.
Fast forward to this morning: Took it off the charger, sent a few texts, and I'm down to 95% within minutes. Of course this frustrated me, since last night I went an hour before it even dropped to 99%. It'll be getting some heavy use today, so the last thing I want to do is leave the house with my battery in the 80% range. I put it back on the charger, and resumed normal usage. Some texting, Facebook, Movies app, Netflix app. Eventually the charging light goes green again. Took it off the charger an hour ago, did some texting, stayed connected to WiFi,and I'm still at 100%. Whereas earlier this morning it dropped 5% in minutes under the same use.
Scratched my head for a second, and remembered that my phone was on and in use while charging last time, before I took it off and got great battery life.
So now, I've set it so my Evo's screen stays on while charging. I also use the Power Control widget to increase the screen brightness to 100% while charging. And then once it's off the charger, just drop it to 50%.
To keep the phone awake while charging:
Menu -> Settings -> Applications -> Development -> And then tap the check box next to 'Stay awake'.
Not saying this is guaranteed to work, and I have no rational explanation as to how this works, but it's definitely helping me. I'm going to do some testing and report back on a few things.
I think you might be on to something. I recently had an experience where my batter was around the 60% mark, I plugged it into my computer for about 30mins - 1hr and somehow it managed to charge to 100% battery in that short time span. Needless to say, the battery drained pretty quickly until it reached some stable point. I'll try the charge with screen on thing when I get a chance.
as odd as this sounds, i have notice the same thing when using my phone while on the charger then taking it off. I use screen cast when i'm at work, so my phone is always plugged into the computer. Once i leave work for the day my phone is usually fully charged or about 80% with moderate usage my phone is usually around 60-70% when i lay down to go to bed. Now on the weekened when i charge my phone overnight, the following day with moderate to heavy usage my battery drops to like 50% within a hour to a hour in a half. So i plug it in while texting or browsing, and when it get fully charged the battery seems to take 3-4 hours to get to 50% with moderate to light use. Weird
I've currently enabled every bell and whistle on my Evo so I can speed up the battery drain. I'm making note of the voltage reading at each percentage (via Battery Indicator), and then I'm going to charge it back up with the screen off to compare these numbers.
I think the issue isn't the charging with the screen on. I think there may be a "bug" that, when the phone hits full charge, it doesn't continue to charge but instead starts using the phone battery. Thus, when you charge at night, it's fully charged for a while, you start using it in the morning and it quickly drops to whatever has already been used (~94-95%). But, if you charge it and take it off soon after the light turns green, then it's fully charged and you're getting the full 100%.
I think there's a problem with the trickle charging.

My testing confirms this theory. I put mine on the charger after work, and the light was green when I went to bed.. the next morning when I unplugged it, it dropped to 90% within a few minutes. Everytime I've unplugged it right after the green light comes on, it stays on 100% for at least 15-20 minutes of use.

That explanation sounds accurate, so instead of doing all this it might b a simple tweak to not have this trinkle effect happen

It was mentioned in another thread that "trickle charge" gives the battery a better deeper charge. Perhaps a 500 or 700 mah charger will do the trick instead of risking a screen burn.
I got got the phone the day it came out and i use battstatt widget and i realized that the battery never fully charges...it always at 99%..and when i unplug it it drops done to like 95% right away..anyone else having this problem??
I haven't noticed it on mine, but coming from the Droid Incredible, I'm a little familiar with battery charging problems. Try this. Charge the battery, with the phone on, until it shows as fully charged. Then, unplug it, shut the phone off, and plug it back in, and see if it continues to charge. With the Incredible, it will charge for another hour before it hits the full mark.
Yes, I am having the same "issue" and it is not resolved with "bump charging" (turning off the phone, charging until full, pulling out plug, plugging back in...repeating several times).
However, the battery life is stellar compared to the Incredible.
I did notice that right after unplugging mine this morning, my battery widget showed it at 98% right away. I'll have to keep an eye on that, and see how that behavior progresses. But I must say, it seems to be doing quite well, even with what I consider heavy use (i.e. playing with it constantly throughout the day, as I'm tweaking it, installing more apps, etc.). I'll have to see once my work week gets going, since I have work email push-syncing to this thing via TouchDown, but so far it looks like I won't have a problem getting through a whole day with it with my normal use.
My battery is fully charging, but the phone seems to stop and start charging, rather than trickle charge. Screenshot from juiceplotter is attached.

Am I missing something here? Why is there no "battery life" data under the "about phone" settings menu on this phone? I see use broken down by source and an indicator of whether it's charging or not, but no percentage remaining, voltage or temperature data like on other android devices. What gives? Do I HAVE to install an app to get this info on the fascinate?
ie. why doesn't this show up on the phone? http://img715.imageshack.us/img715/2236/dscn0042r.jpg
Yes I've been noticing too that the battery indicator can be very off, I've been watching it very closely. Cases such as yours where it thinks its more full than it really is, and cases where the indicator even JUMPS up. Once the battery thinks it's full, it will not charge further leaving you undercharged all the time.
So far I've got I think I've got it working, and have yet to notice any issues. I previously noticed that the battery indicator seems to be more accurate when the phone is off. So what I did is: I completely discharged the phone, then fully charged the phone without turning on the phone. Now been using it, haven't had any obvious issues with faulty battery indicator and I really feel that it's charging completely now. On a sidenote, I think charging with a laptop can throw it off, so always try to use the AC adapter. Hope it works for you too if you give it a try.

I get the same from juice plotter. I have read certain battery types should not be continually charged after they reach 100%. This appears to be a safe guard.

I am LUCKY to get 8 hours of battery life on my brand new stock Epic.. I usually get 4-6 hours. It will NOT last through a normal day of work without putting it on the charger around lunchtime. I take it off the charger around 6:30 AM and I am usually home by 4PM and have to immediately go and charge my phone.
Even if I put it on airplane mode, kill all running applications, and shut the screen off to standby, the phone still seems to suck battery life down very quickly (~5% in 20 minutes on airplane mode, wtf???).. So airplane mode doesn't help.. And I really DON'T want to put it in airplane mode to conserve battery because then my phone is completely useless -- it won't even ring when my wife calls..
Is my battery defective? Please tell me it is... This can't be right..
Are there processes still running that use lots of CPU, even when the stock sprint "task manager" program shows that nothing is running? Is there anything I can do to improve this if I root the phone? How about custom roms? I would really like to run Froyo/Gingerbread anyway.. If anyone has any suggestions to help to make my battery life not such an EPIC FAIL, I would greatly appreciate it.
EDIT: Also wanted to comment on the SLOW CHARGING. With the stock Samsung wall charger, it takes at least a couple of hours to get a full charge. With a USB cable plugged into a PC overnight, it only gets to about 50%. Compared with my previous phone, the HTC TP2, this is really really REALLY slow. It charged in 30-60 minutes and the battery lasted much longer.
I did notice that Samsung only provides a 0.7 amp charger, versus a 1.0A charger for the TP2. Why does Samsung limit the charge current like this? And apparently there is no nueBattery mod driver for android
UPDATE: JuiceDefender looks very promising. Installed the free version and my battery is only down to 95% after one hour. Thanks for the suggestion.
FWIW, I'm getting about the same 8ish hours on mine running DK28. I'm losing about 4% an hour without touching it. I'm seeing some people claiming insane battery life (18 hours with heavy browsing on wifi) I wish I knew how they were managing that.
Wait, it won't even ring when you're wife calls? and you're complaining?
First, the airplane mode means you switch the phone to airplane mode first then switch it back so you won't have time without signal problem which can cause battery drain.
I am able to get 10+ hrs at least by doing the following
1) use airplane mode trick so no TWS
2) use titanium backup to remove a bunch of stock junk
3) use titanium to freeze certain applications (DRM, MediaHub, Qik etc)
4) Have as few applications as possible that constantly pull data
Just yesterday I had 1 day 17 hours before switching
Yesterday when it finally gave up the ghost with the battery indicator blinking i checked my stats.
I had 1 day, 17 hours unplugged. Screen time was around 2 hours and some minutes. I had 45 minutes of talk time.
One thing i will add is I purchased a charger with two batteries off Ebay. Previously when charging with the stock charger as soon as I pulled it off the charger it would read 97%. With the seperate charger it reads 100% for quite awhile before it starts to drop.
And for the record I purchased this charger and two batteries of Ebay for a winning bid of $0.01, plus $9.95 S&H. It was a steal in my opinion.
Unless you are getting near 12 hours of battery life, one of 3 things is occurring:
1) You are using the phone an insane amount
2) You messed something up
3) The battery is defective
For the record, its almost always number 2.
I suggest doing a Factory reset, which will wipe everything off the phone. Then without installing anything or setting your facebook to update every 15 seconds, see how long the battery life lasts. If it is still only 4-6 hours, then your battery is most likely defective.
well of course it won't ring if your wife calls if its in airplane mode. That radio is turned off.
8 hours? That's it? I wouldn't call that normal, but that's just me...
I just plugged my phone in after 4 1/2 days (108 hours) running on a stock 1500maH battery, running Quantum Rom 1.5 (DK17), no special apps running to disable data (aka Juice Defender, etc.), not in airplane mode at all, with the DRM software running, in other words, a more or less 'Stock' configuration (taking into account any differences in the base Rom).
Granted, I barely used the phone in the last 4 days though

Like I said, barely touched my phone in the last 4 days... been feeling a little under the weather so have been at home a lot and in bed doing all my internet stuff and gaming (pogo) on a laptop instead of on my phone.
Since I updated to the leaked Froyo, my battery life has plummeted. It lasts maybe 1/3-1/2 as long as it used to. Turning off 3G has helped immensely though, so that must be the culprit. I used to be able to leave 3G on while at work and make it to bedtime before having to charge it. Or if I shut it off at night (which I usually do), it would make it through my commute to work the next morning. Now, I'm lucky to get through the work day unless I turn off 3G. Huge difference in battery life for me since updating. I'm hoping they fix this in the official release of Froyo.
Well, I've recently found out that if you flash via update.zip while the USB is plugged in, you'll mess up the battery calibration of your device. This is what I did, and i'm pretty sure the cause of my problems. I did find a fix, and here it is:
siliconaddict said:
This is the procedure that works for me:
The following steps should significantly extend the battery life on your phone:
1. Let the battery drain close to empty (5% or less).
2. Connect the phone to the charger (AC or USB, USB is better) while powered on and allow the phone to charge until the notification LED is green, indicating the device is fully charged and untill the voltage is at least 4187mV. A higher voltage like 4192mV or more is even better. Use a tool like Overcharged or Battery Indicator to monitor this. Note that a green notification LED does not automatically mean that the voltage is good too.
A higher voltage means in practice that it will take longer to discharge, a lower voltage means that the battery will discharge a lot quicker! The difference can be quite significant!
3. Disconnect the phone from the charger and power it off.
4. Reconnect the phone to the charger while powered off and allow the phone to charge until the notification LED is green. The notification LED may turn green immediately. Leave it on the charger for another hour.
5. Disconnect the phone from the charger and power it on.
6. Once the phone is powered on completely (has restarted fully) wait 2 minutes and power it off again.
7. Reconnect the phone to the charger while powered off and allow the phone to charge until the notification LED is green. The notification LED may turn green immediately. Leave it on the charger for another hour.
8. Leave the phone on the charger and reboot into the ClockWorkMod recovery menu and wipe the battery stats via -> Advanced -> Wipe battery stats.
9. Disconnect the phone from the charger, restart the phone and start using it as normal.
From then on always let the battery drain close to empty (5% or less) as often as possible and then charge untill the voltage is at least 4187mV. A higher voltage like 4192mV or more is even better.
Normally you will have to do this only once. However, on all Android ROMs, if you flash a ROM while charging or during the first boot screen on, first boot mucks up the levels Android thinks the phone is at, i.e. Android will think you’re at 100% when maybe you’re only 90% or whatever. So in theory you will need to repeat this every time you flash a ROM while charging!
Better is to make sure the battery is charged before you flash a ROM and just remove the USB/charge cable before you flash a ROM. Put it back in (if you must) after the first boot screen (when the custom screen or whatever shows).

So combining the two bits of info we've compiled, the best way to calibrate your battery is as follows
1: Charge phone whilst on till LED is green.
2: Disconnect phone from charger, power it off.
3: Reconnect to charger with phone powered off and allow to charge till LED is green.
4: Disconnect the phone from charger, power it on. Once completely powered on, turn it off again and reconnect to charger until LED is green.
5: Reboot into recovery (back button held at same time as power button) and wipe battery stats.
Battery should now be calibrated.

From what I've been told, you don't have to wipe the stats (you need root to do that) but it helps if you can.
I think this may also stem from interrupting the inital charge of the device. I know I did this on both my wife's device and mine (plus my added fubar of flashing with the USB in). Anyway, hopefully I can report some good news tomorrow.

I get 4 or 5 hours if that. I can barely make it to 6. But i probably use my phone more than the average person. Because i take public transportation and browse, stream, email and have 4g connected on my commute back and fourth.

I've been running JuiceDefender for about 5 hours now and I am loving it.. I still have 75% and I can still receive calls just fine.. It turns off data when the screen is off, but turns it on at scheduled times (default is 1 min every 15 min) so that your emails/twitters/etc can update like normal. The paid version has even more features so I bought it..
Never mind im dumb for not reading his post. Already answered my question sorry.

Decided not to quote the whole thing but I'm in the process of doing this right now! Took 2 hours to drain my batt from full (running everything and keeping my phone searching for gps constantly in a place where it would also be searching for signal makes quick work of a battery!).

Yes, with juice defender I can receive calls and my gmail/twitter/facebook/etc. are all already up-to-date whenever I pick up my phone. It works exactly as before, except my battery is not constantly being drained now.
I guess the downsides are that I might not get a new email notification for 15 minutes, and that there is a service running in the background that may cause some slowdown. Neither has been a problem for me so far. I highly recommend this application for Epic 4G owners. Problem solved, basically.
I usually get 12hrs with moderate use (~2hrs with screen on, half of that is usually on the browser). I turn background data off bc I don't have a twitter and I rarely check Facebook so when I do I just use the browser.
I also noticed that wifi burns more battery on DK28, on 2.1 I would hardly lose any battery on standby with wifi, now I get a 3-4% drain per hour... But with 3g on now I lose less then 1% an hour, it used to be a battery hog.
Hello all,
Recently i've been noticing that my GS4 battery is draining too fast, i think that it's time to recalibrate it. Since my phone is not rooted, i have searched for guides on how to recalibrate the battery.. and i found this one:
To calibrate your Android phone battery correctly:
1-First drain your battery down. Let the device switch itself off naturally. You will know if it is completely dead because it won’t switch on again.
2-Place the phone ion charge while it is turned off. Allow it to charge for at the very least 2 hours, if not 4, until the battery meter reads 100%
3-Switch on the phone while the charge is still connected to it. When your phone is on the home screen, leave the charger connected for a further 2 minutes before removing it.
4-Repeat the above steps twice more, always allowing the phone to completely discharge first.
The reason for leaving your charger connected is to allow the configuration files to update with the new, correct charge values. Some of the best ways to avoid battery usage is to make sure all connections are turned off when they are not in use – Wi-Fi, Bluetooth, GPS etc. Make sure your screen locks down in under a minute when not in use and that your screen is not set too bright
My question is.. is it safe to turn on the phone while it is charging? is it safe to turn on the phone when it is plugged to a charger while it is off?
Thank you in advance.

Hi
Yes and yes
BTW I do not believe to much in those battery calibration methods , as far as i know a new file is generated each time you switch off and back on
You can charge your phone in any status, on, off, flight mode, playing games etc.It will only affect your charging speed.
As for calibration - I have heard about such thing and try to discharge my battery till some 1-3% and full charge at least once a month. Don't know if this helps. I think also important is the environment temperature and how you discharge the last percent.My suggestion is that last percent must be discharged as slow as possible - with screen locked let it die natural way, with normal usage, very slowly. I and other usually switch all possible things to drain battery faster at this stage. That seems wrong on my personal opinion.

NO NO NO
Draining your battery is BAD!!! Draining it below 0 is the dumbest thing you can do. That damages your battery. Whoever made that "guide" has absolutely no understanding about his battery.
Calibrating is easy.
Charge to 100%. Pull your battery. Put battery back in. Charge again until full when powered off. Volia calibrated.
Though it will probably not help. My guess is that you just need a new battery (if it's no software problem).
I'm not sure if my problem is with OxygenOS or Nougat, but I've scoured the internet for months and haven't found an answer
I have two problems that I think are linked to doze mode on my device, and they both occur under the same conditions. First is my alarm clock (Alarm Clock Xtreme) doesn't work in the morning, and second is my Samsung Gear Fit 2 needs manually reconnected each morning. And through troubleshooting I've determined the problem occurs under rather unique conditions. The problem ONLY occurs when my phone is plugged in and sits overnight (so fully charged sometime during the night). Which is most nights, because I want a full battery in the morning.
But if I happen to go to bed and leave the phone unplugged, the alarm clock WORKS in the morning and the smart watch stays connected all night. So unplugged overnight, no problems. Plugged in, alarm clock won't work and Bluetooth connection to smart watch is dropped.
I haven't been able to find an answer in the 3 months I've had my OnePlus 5. Any thoughts?
Specs: OnePlus 5, Oxygen OS 4.5.10, Nougat 7.1.1.
I can also move this post elsewhere if there is a more appropriate area of the forum for this question. But I don't have this problem with my old device.

I actually had another alarm clock app before, that was doing the same thing. And I don't really have an alternate application for the watch.
I've researched this fairly extensively and have only been able to grasp small nuggets of insight. I did find one source on xda (but I can't remember where I saw it) that talked about doze mode acting funny when the phone is plugged in to charge. Basically an inability to wake from doze under certain circumstances.

You can always enable Developer Options and choose the option for the screen to stay awake while charging which should also keep your phone awake. You can also disable Doze completely in Developer Options.

Thanks! I don't want to disable doze, but I might try that other one. My other quick fix I juts thought of is to use a timer switch or smart switch to have the charger shut off after an hour. That's enough to give me a boost, but not fully charge. I tried it last night and everything worked this morning. Though my battery was only at 60%, it was better than nothing.

It's recommended these days to keep your battery charged between 40%—80% to prolong its life and not keep the phone plugged in overnight like in the old days. I charge mine to 80% before going to bed.
If it's actually a Doze issue I don't understand why it wouldn't happen when the phone isn't plugged in. Do you have a screen saver enabled?
Fellow OP5 user here, I have the EXACT same problem.
If I leave the phone charging for long time and doze kicks in, the phone basically shuts down for all purposes until I unlock it with my pattern. Meaning, only the built in alarm (that works even with the phone turned off) will work. Any other (Timely, radio...) won't.
Now here's the kicker: sometimes the deep sleep will cause a weird bootloop, upon which the screen will indefinitely hang on the spinning logo, with the screen turned on, requiring a reboot. And of course this makes the alarm not sound.
This last bit happens at random. If I disable the screen sleeping in Dev options, the alarm will work but when I wake up the pattern input screen would be there, after all night on, which isn't really healthy for the screen.
Turning doze off makes this problem apparently disappear, but I need to investigate some more to draw conclusions. For the time being I sleep without charging, quick charge and the phone's great battery makes it unnecessary to keep it connected all night.
Another fun tidbit of this deep sleep mode: it stops USB tethering. I would have imagined a wakelock in there, but apparently there isn't.
For information : I use vanilla kernel and OOS. I have Magisk on and Gravitybox via Xposed Magisk, but other than that I have nothing particular going on.
I've been hearing that from other sources as well, about not letting it sit overnight on the charger at 100%. Which is why I think I'm gonna keep using the smart switch of my nightstand charger. The OnePlus Dash charging system works great for a quick charge anyways, so having 100% fully charged to last all day long is no longer necessary. I have a normal USB cable at my night stand, so it's a slow charge. If I set the timer to stop after an hour it at least gives me a small charge overnight, without overdoing it. And I have dash charger at work to give me the full quick 20 minute charge that puts me at 60-70%.
No I don't have a screensaver running. It is weird that the phone locks in the doze mode for the alarm and boots me off my watch's BT connection, but only when plugged in and sitting at a full charge for an extended time (haven't stayed awake all night to test just how long it has to sit). But that IS what it IS. Those have been confirmed as the only conditions in which this problem arises. I've been using the smart switch for 3 days now to keep my phone from going to and staying at 100%, and the alarm clock is working again and the watch is staying connected.
It's not that it's a big of a deal for me to have to use a work around like this. I don't mind. But I hate finding a glitch in something and not being able to truly "fix" it. Work-arounds work. But they don't actually solve the problem. This is just a gripe I have in general whenever something like this happens. It's in my nature to want things to work properly. Which is why I haven't had a non-rooted device in at least 5 years. I NEED to have the ability to fix the [email protected]$$ sh1t the software developers and phone manufacturers screw up. Of course, that's probably the number one reason xda exist. This open up the full potential of these devices, because the manufacturers are either too dumb or are financially motivated to not fix things (ahem...Samsung). Thank you everyone who chimed in with advice. I appreciate it.
It has been my experience with this phone so far that doze mode doesn't work. At all. I regularly have widgets that won't update even though I have doze turned off...
Just one of the many annoyances that has me thinking about finally rooting and getting rid of this garbage os...
