Bad Problem with the Battery
i have the TP and the bettery have a big problem it's ended in about 5 hours with no use.
how can i fix it?
is there any program to increase the use or tweak the settings?
from 5 hours no
change the battery
You have either some app running which consumes a huge amount of power (really huge! Even if you use TP as video player with the screen configured to full brightness TPs battery lasts for at least four to five hours). Or your device has got a faulty battery (which would probably be more likely).
Are you by any chance using Wayfinder Navigator gps-software? I found (the hard way) that this software doesn't close the GPS-unit in the phone automatically when you exit the application. Even after a soft-reset the problem persists. This will drain the battery in pretty much 5 hours. The solution is to manually close the GPS-connection in the WF Navigator program settings every time you exit the app (and hope for a fix ASAP). I've already reported this to Wayfinder, and they're working on it.

I was using a GPS related app the other day and the same thing happened to me. Try and find out what hasn't shut down properly...
10X for all
melcul-i think i will send an email to HTC about that
DeepThought-i checked if there is any programs that running but nothing is running acording to X-buttom 35% memory in use.
aBE-One- i am not using that app.just using QuickGPS and Nav N GO IGO8 and they are close.

what aBE-One is saying is that on his phone he had a similar problem, the software was closed but the GPS command remained active thus draining his battery, so your IGO8 might be shut down as software but there is a chance that the GPS hardware is still running in the background for no reason. go into your com manager and turn off GPS and that should resolve the issue

Exactly the same happened to me, after a full charge it took only 5 hours to an almost complete discharge.
I bought TP 1 week ago and it came with radio 1.02.25.17 with no battery issues at all but with the GPS issue -not finding sats-. After upgrading to 1.02.25.28 radio ROM, the GPS now works ok with TomTom, GPS test etc, but the battery now drains dramatically even in standby with no software running and all radios off except phone.
Is possible that the GPS radio stays on even after closing GPS software? In that case, is there any way to manually switch off the GPS module?. In TTN there's no a button to do this.
Mine too..
But i've observed this drain even before upgrating to radio 1.02.25.28
In 40 minutes from 78% to 69% (9%), in stand-by mode (short press power) without any running application!
And I've done 3 or 4 full discharge-full recharge cicles...
LE: No active moderator here? There are plenty of battery problem topics.. why not merge them? It's hard to chose in which one to post... Also, that's not the only case. See GPS related bugs, opera, etc. Too many duplicate topics.
Ok, more info:
I've drained the battery completely till the device turned off then I've left the phone on charging overnight (device turned off).
After about 9-10 hours I've unpluged and turned on the device. Used for 1 hour and 25 minutes in total (about 1 hour for browsing - not downloading, so data transfer was not continously - and the rest for music). With "Auto adjust backlight". The battery level gone from 100% down to 68%, so 32% battery drain in less than a hour and a half!!!
Now, after 4 minutes (device was in standby - eg: short power button press), I wanted to check something and the battery metter was on 66%... so 2% in standy/idle mode in just 4 minutes?!
@l1234 any updates?

That all sounds correct. I can be typing emails/sms with WiFi and phone on (not actually doing anything), drains about 1% per minute.
I read the other day that the percentage indicator is faulty. Some people have reported the battery draining down to 10% in a very short time, but then the meter will stay at 10% for hours before going down to 9%, etc. Has anyone else noticed this? If not, look for it and see if it happens to you. Also, open the power meter in the settings options and verify that it shows the same battery level. I've had that happen to me already where it would say 50% in the title bar but the power options still show 3/4 of the meter!

I have noticed that the battery percentage indicator does this. All in all, my device has better battery life after flashing a custom ROM, keeping screen brightness under half and leaving off bluetooth or wifi if possible. my battery will stay at 100% for hours, but if i soft reset, it drops 10%. other times it will drop right away but stay there. It really does stay at 10% or so though for ages before it drops further.

I was brosing via 3G/HSPDA connection. No WiFi/BT on.
Now, it seems that the drain in standby time is OK (haven't done something special, same processes opened.. maybe just now the battery can be used at its full performance, after some charges/discharges) - BUT when using the device the battery drains quite quickly..
I give you an example.
Battery was 100%. Browsing the internet with IE & Opera for 1 hour. Battery meter was on 75%. So 25% in one hour... tooo much... The display backlight is set to "Auto adjust".
Again, I'm not using Wifi/BT, push e-mail, etc. Just normal browsing (without downloads) with a 3G/HSPDA connection.
I've had my Fuze about a week and I've been testing out many of the available ROMs. I've noticed disturbing trend and want to know if anyone else is seeing this problem, and if so, how can we fix it? It seems like anytime I install a Raphael based ROM, I start to lose battery power at a fast rate - about 10%/hour, maybe even faster. With a cooked ROM based off the ATT Fuze code base, I do not have this problem. I get this even when I install the keyboard fix, etc. and I am doing a hard reset after install to no avail. Any help, input, thoughts or shared experiences welcome.

I am using PROven's latest 1.4 rom and the battery is amazing!!! I loaded it last night, charged it up around 9pm and at 5pm today I am still at 70%!!!
I've noticed this as well. I first go suspicious when after a long flight in airplane mode the battery drained significantly.
No I am in all day meetings this week so I am trying several combination to see what sucks juice and what does not by keeping the radio out of the equation.
So far it seems that RomeOS is a battery suck while NATF is not. This is with the device doing nothing but sitting there with no radio activity.
I've notice that the stock .32 radio on the fuze is the culprit (at least on MY fuze). After I downgraded to the .28 radio the battery life has easily doubled!
@NRGZ28
Which .28 radio do you mean?
1.02.25.28 - Extract Official Shipped Orange ROM ESN 1.90.75.3??
I'm using ROMeOS with 1.02.25.28 radio and I have pretty good battery life on the Fuze. I've also used some other ROMs here and no issues either in regards to battery. Is your data connection on constantly or is it configured to disconnect after X # of mins?

Hello my Friends.
Normally my Pre Plus on Idle mode from 12.00 AM to 3.00PM consumes 10%, Really I don't know how much I consume using it for play and calls, but I charge it every 3/4 day (6+6+6 Hours=18 Hours) Of use till my Battery drains completely. I have the next installed:
Patches: 38
App Installed: 34
Linux App: 13
Web Server running over 3G.
AV Harrier II: at Power Up Over-voltage 1.005Ghz
Bright solution:
This is most of the drain of the Battery sol. you should put this less than 40%, The Pre-/+/2 /Veer has Better bright than other Devices even in 20% tested by myself.
IM Solution:
Do not use the Stock IM because is like bugged or something like that, makes the battery drain 7% than normal drain.
Email Solution:
Receiving a mail every time you get it is not so good for the battery because is always attempting to the server, the solution for this is get Mail manually or every day.
Bluetooth and GPS:
Really I don't see much use for Bluetooth since on WebOS can not do File Transfer, but WebOS 2.x made a change and now we can use Keyboards, avoid turn the Bluetooth if you're not using it, and GPS turn it off, is other core of Battery Drain, just turn it off if you're using it and when you're done, OFF.
WiFi and 3G
Really I haven't see difference between two of this because really the 3G consumes more than WiFi but only if you're using the things I said before
Airplane mode, I never tested this but some people says that Battery drain less if you use this mode when you're going to sleep.
Hope this was helpfully,
Thanks and have a good day
Executive summary = You always want "Keep Wifi on During Sleep" set to "Always" if you care about your battery life.
In post #17 in the "P6210 - Huge Battery Drain on ICS" thread iosandroid found that setting "Settings->Wifi->Menu->Advanced->Keep Wifi on During Sleep" to "Never" caused battery drain. Since I feel this is big bug and my mom told me I'm special I thought I'd start a new thread with some more details on this problem, a more descriptive thread title to highlight this issue and a few questions of my own.
I have a Samsung Galaxy Tab 7.0 Plus (aka GT-P6210) WiFi only tablet that had HC (Honeycomb) when I first got it. To save battery I changed "Settings->Wifi->Menu->Advanced->Keep Wifi on During Sleep" to "Never" (actually think the wording was a little different back in the HC days, but you get the idea). I'm not sure if/how much this helped, but it didn't hurt my battery life.
Shortly after upgrading to ICS (Ice Cream Sandwich) I noticed my battery life was worse. Apparently I wasn't alone since "iosandroid" (see above) had the same problem and solution. That is, if you set Settings->Wifi->Menu->Advanced->Keep Wifi on During Sleep" to "Never" or "Only when plugged in" your better drains much faster when you're tablet is idle. How much faster? In my tests setting this to "Never" drained my battery by 3.10%/hour. If I leave this at its ICS default of "Always" my battery only drains at 0.27%/hour, OVER 10 TIMES BETTER (idle) BATTERY LIFE! See the bottom of this post for a listing of my battery drain tests.
By using "CPU Spy" I could see that with "Keep Wifi on During Sleep" set to "Never" my tablet would never go into deep sleep, but with it set to "Always" my tablet would spend almost all of its time in deep sleep. GSam Battery Monitor showed that "Kernel (Android OS)" was using up most of my battery when this problem is occurring.
This problem isn't limited to ICS, I also got the same results with JB (Jelly Bean). Specifically I used "AOKP Jelly Bean Milestone 1". With stock ICS the default setting is "Always", so only people that mess with their advanced settings will be affected by this. Note that I believe that an OTA upgrade from HC to ICS will retain your previous settings for this. In JB (at least AOKP JB), this problem will have a much wider reach since "Keep Wifi on During Sleep" defaults to "Never".
Now on to my questions:
-Does anyone know the scope of this bug? Does it only affect the P6210, or Samsung devices, or every Android device? iosandroid reported having the same problem with his phone.
-Do I have to open a tech support case with Samsung to report this bug, or is there a better way?
[Battery Drain Tests]
VERSION Keep Wifi on During Sleep? DRAIN RATE
----------------------------------------------------------------------------------------------
HC Always 1.00%/hour (lost 2% total over 2 hours)
HC Never 0.50%/hour (lost 1% total over 2 hours)
ICS Always 0.27%/hour (lost 2% total over 7.5 hours)
ICS Never 3.10%/hour (lost 24% total over 7.75 hours)
JB Always 1.0%/hour (lost 1% total over 1 hour)
JB Never 3.52%/hour (lost 81% total over 23 hours)
-Legend
--HC = Stock Honeycomb (Android 3.2)
--ICS = Stock Ice Cream Sandwich (Android 4.0.4)
--JB = AOKP Jelly Bean Milestone 1 (Android 4.1.2)
-Setting "Keep Wifi on During Sleep?" to "Only when plugged in" behaves the same as "Never" (i.e. it has same battery drain problem)
-Yes, I know my testing time periods vary wildly, but I'm too impatient to wait a day for each of the tests. For example I'm sure JB's "Always On" loss rate is much closer to ICS's.
All I can say or add to this my tenderloin HP touch pad running cm is the same keep wifi on always drains the battery slower than never.
IMO, it would be because of 3G activating when the wifi turn off during sleep.
Try doing your test in Airplane mode to isolate the activation of the Phone radio and stick only to WIFI during your comparison test.
EDIT: ooops! sorry, it just occured to me that you've got a P6210 and not a P6200. My bad.
Airplane mode uses more battery than WiFi always on

Yup, my tab is WiFi only. However I did actually test it in airplane mode and found that the battery lost 0.40%/hour (lost 11% total over 27 hours) with airplane mode enabled. This is still worse than the 0.27%/hour you lose when you just leave WiFi on (Keep Wifi on During Sleep? set to Always). This airplane mode battery drain was also unexpected to me, but in googling it seems like this is a common problem.
One last test I did was to manually turn the WiFi off. When I did that the battery only drained at a rate of 0.11%/hour (lost 1% total over 9.5 hours). I should test that longer to get a more precise number, but my short test was good enough to show that manually turning WiFi off does actually save power (it's about time something worked as I expected it to .
My next planned test it to use something like AutomateIt to automatically turn off the WiFi after the screen turns off to see if I can automate the WiFi battery savings.
My GT-P6210 also has the same issue after installing Elements HD rom. I never had this issue even after upgrading from honeycomb to ICS stock.i

If you know how, try looking into the build.prop. you'll find that stock wifi. supplicant_scan_interval=15. try a higher number like 90 or 180. this basically lengthens the time for wifi network searches from 15 secs to 90 or 180 seconds respectively.

I could probably figure out how to change that, but I've decided that just leaving WiFi on all the time gives me good enough battery life. I enjoy troubleshooting these types of technical problems, but unfortunately I must return to debugging my three year old daughter's Dravet Syndrome. Her cognition is deteriorating, so I'm hoping to find a solution or workaround soon. If any of the multimillionaires that read this forum want to fund a cure for Dravet Syndrome, head on over to dravet.org or dravetfoundation.org
I've got this issue on a Chinese Tablet running JB 4.1.1. After some investigation the conclusion I've reached is that the settings are mislabled on the GUI. "Always" results in disconnection from the SSID 15 minutes into sleep (although WIFI is still 'ON'). "Never" keeps WIFI on and connected indefinitely, and if autosync is also on you'll get lots of wake-locks and reduced standby battery life, particularly if you have location reporting on and google maps installed.

Interesting results, but that wasn't my experience. For example with WiFi always on my tablet does stay connected to the network all the time. All of these weird issues is about enough to make you want to buy an iPad.
I recently noticed after the latest update excessive battery drain as seen in screenshots posted below. I have tried a factory reset and then unlocked bootloader to root and added greenify to try help save my battery. Does anyone have any tips on what else to try?
Have you tried to figure out what the Miscellaneous drain is? At least on my tablet I don't have that category in battery usage.

If by "new" you mean recently flashed/factory restored, then I'm not sure what to say. Even after flashing a recovery image I've never noticed that category. The only reason why I asked was because I assumed that was what you were referencing as being excessive.
If you were referencing the 24+ hour battery life graph shown in your screenshots, then that seems about right. Unfortunately the tablet has never been known to have stellar battery life unless it's on battery saver 24/7.

Seems about right?! He had 7min 2sec screen on time. If thats "about right" to you... you need to RMA your tablet.
Clearly whatever "Miscellaneous" is, is his issue.

Ok, so I noticed the very same thing when I got my Shield, I haven't rooted (I had on KitKat to restore some backups, then didn't do it again in Lollipop yet). I contacted Nvidia's service via livechat and got this answer. It did some considerable difference, although I still think it's draining a little too fast, but my old tablet had a pretty strong battery so I was just spoiled by it it seems >.<
So here it goes:
Nvidia Shield Callibration: (this takes a while)
You will have to calibrate the battery for just one time and observe the device battery backup for 2-3days to see the changes.
1: Drain your Shield tablet battery by using it normally until it turns off by itself.
2: Power-on your Shield tablet, if it wakes up and if you see some power left, follow step 1.
3: If Shield tablet is now drained to the point it can't wake up, set the device to charge for 7-8 hours.
The device should remain off when you set it for charging here.
4: Unplug the charger after 7-8hours, power on and wait for the battery charge to drop down to 90-95%.
5: Once the device battery drops down to 90-95%, plug in the charger and charge for one complete hour.
6: Unplug the charger once the device is fully charged.
7: Go to Shield settings > Shield power control > Apps> select optimize all option.
8: Go to Shield settings > Shield power control > system>
• Set the brightness to auto.
• Change the sleep option to 2 minutes of inactivity instead of default 10 minutes inactivity.
• Change the processor mode to either optimized or Battery savings.
• Check the WiFi optimization on.
Observe the device performance and report to us if you are still facing issue with the battery backup..
And then they gave me some tips for better battery life in general, I follow them (mostly) and my battery seems to hold on decently:
1: Always use the Shield tablet charger and not the computer USB ports or any other charger as the power specifications vary from the device to device.
2: In case if the charger is missing, use the back port of the desktop computer to charge the device instead of front port.
3: Always remember to exit the application instead of tapping the home button which will continue to run the application in the background.
4: Restart your Shield tablet at least once in a week. This will refresh the device making it work faster and efficient.
5: Connect the charger only when the battery comes down to 15% and unplug the charger only when it reaches 90% or above. This will reduce the number of charge cycles which will make battery last longer.
6: Use a third party app manager like Clean Master and free the memory at-least once a day to keep the device running faster.
To notice if the battery is fully/optimally charged when the device is off, look for the led indicator next to the charging port. It should be green, indicating it is fully/optimally charged
OTA update to 9.0 available a couple of days ago so I let it install. Since then, I've seen considerably quicker draining of the battery, with my usage of the phone being much the same as before. For example, when I went to sleep last night the battery was at 64%, and there were no apps running according to a swipe up from Home, but when I woke this morning, battery was down to 2%. I normally charge once a day, and previously the battery was hardly ever below 50% after 24 hours - I'm a pretty light user.
As an aside, with 9.0 there no longer appears to be possible under battery usage information in Settings to see the percentage of battery that has been used by the various apps and processes.

Ok here. 62% drop over night doing nothing suggests you have a rogue app in there. I'm assuming you have ok cellular coverage and nothing has changed there by coincidence. I would reboot and force close every app you have that's not essential overnight and try again. Swipe up from home and clearing those apps doesn't force close the apps. Greenify is an app that (in manual mode) will make it easy to select as many apps as you want and force close the lot of them. If that improves the situation you can then begin to work out which app(s) might be doing bad stuff whilst you sleep...
Battery on my P2 has significantly improved with Pie even if I didn't have any major problem with 8.1 either. Overnight drain 3-4%. After regular use after a full day I easily exceed 5h SOT. Everything stock with just Greenify in non root mode. I couldn't be happier, best Android release so far for me.

I've had my p2 installed with PIE for about 2 days now. I suggest giving it a week (which is what I'm doing) and then getting a full overview of how my battery is performing. Usually, after any major OS updates, being that apps are trying to utilize your resources and a new version of Android would try to allocate and learn your usage (in this case battery), you'd get a much better definitive idea of your overall performance.
I also think that since its now available, turn on Adaptive Battery mode. After a day of upgrading the OS, Adaptive battery at my 26 hr mark of upgrade said that one of my apps was taking in a lot of resources to be used in the background (ES File Explorer). I made AB to stop ES from taking battery resources.
So in conclusion, if it a week and then you'll be able to get a better overall understanding of whether your battery REALLY has gotten worse or better.
Hope this helps!
Interestingly, my battery was dropping really quickly too after the update to DP3, I switched off Adaptive Battery and it fixed the issue completely.
I tried it again with Android Pie and the issue resumed, so I turned it back off. Maybe try this too?

Exact same problem here after updating. Even tried a factory reset in case it was an updating issue. Same problem. My battery is currently at 43% 4 hours after a full charge. And I've barely used it. This is really poor.
No new apps installed.
My Oreo battery life was great. I'll try shutting off adaptive battery as suggested - but seems a real shame if one of the flagship battery saving features is doing the total opposite on Google's current flagship phone!
Doesn't seem to be a massively common issue so not sure if a likelihood of a patch either
Just a quick update - Google play services has now become the biggest drain on my battery, just as it was before I factory reset after the first install...
Anyone else had the same?

I had the same issue and did the same thing... until dp3 and my battery usage was terrible again even with adaptive battery turned off. I ended up turning it on again and after about a week my battery usage was back where it was before. So there doesn't seem to be a magic bullet here. FWIW app usage offered no insight as to what was causing the drain in the first place.

THIS.
I got like 8+ hours of SOT.... no mobile network though, all day wifi use only.
I have this issue. Dropped about 40% over night. I found that turning wifi off stopped the drain completely. I did not have this problem with Oreo at all so it's not the networks im connecting to. Weird thing is this did not happen when I first installed Pie. This started happening about 3 days into installing. Also, I put it in safe mode and saw the same drain with wifi on vs off.
Hi guys,
I seem to have fixed my terrible battery life!
The below might be worth a try if you're still suffering from it.
I noticed in GSAM that RCSphone was the front runner in battery drain so did a little research and found this site.
SOLUTION: Turn off app preview messages (settings / google / app preview messages). Apparently its only function is to allow Allo messages to be received without the app. To me, totally pointless as i don't know - nor have ever met - a single person who uses it.
I've gone from draining 8-10% an hour (screen off) to around 2.5%/hour and from 1hr 35 total SOT to 3hrs 39 minutes with 32% left (and an hour of that was Google maps navigating, so a proper work out for the phone).
Do give it a try and let me know if it works for you.
Although there's room for improvement (idle 2.5%/h seems high to me!) and it's ludicrous that I should have spent several hours finding a fix for this on 100% stock android, I'm very happy to have a usable battery life back again...
Adam.
UPDATE: Seems like in the night I lost 40% again. Idle drain climbed it's way up to 5.6% in the night. Still an improvement from where it was before, but not quite as good as it first appeared...

Ok here. 62% drop over night doing nothing suggests you have a rogue app in there. I'm assuming you have ok cellular coverage and nothing has changed there by coincidence. I would reboot and force close every app you have that's not essential overnight and try again. Swipe up from home and clearing those apps doesn't force close the apps. Greenify is an app that (in manual mode) will make it easy to select as many apps as you want and force close the lot of them. If that improves the situation you can then begin to work out which app(s) might be doing bad stuff whilst you sleep...

@Burkules I drop 0.4 - 0.7%/hr over night with Bluetooth off/Wifi on/strong cellular signal. Much the same as it was with Oreo. Not quite sure why's there's such a big range (almost 2x) but either way it's ok for me. Did you try the technique above?

Cheers for getting back on this.
I left it on safe mode the other night and it still drained absurdly fast, which suggests to me it's a google system drain rather than rogue app, but will try again with app preview now switched off. Likewise will try greenify again and report back.

Likewise maybe app preview set to off will help me even more. If I recall correctly rogue apps can cause some google system apps to wake up, but perhaps not in safe mode...

So, switched off adaptive battery again (i'd enabled it after my short-lived miracle recovery the other day) and now I'm down to 4%/hour. Which is better but still really high for idling! Cleared cache and data in Google play services for good measure too as it still comes up super high on the list of battery drainers.
Booting into safe mode now to check the drain without adaptive there and will report back...
UPDATE: Exactly the same drain in safe mode. This is a straight up google problem....

Have you tried to force close every app you've downloaded too?

Haven't tried this - but if the battery drain is the same in safe mode (with only google/system apps running) I can't see how it will make a difference. Ill be in rehearsal for several hours today so will force close everything and will then be leaving my phone idling for a few hours anyway.
I signup up to the google play services beta yesterday, and google play services no longer appears as one of the top battery users... but the battery drain is the same and the numbers given in *all* battery apps (Gsam/accubattery/system) don't add up to anything close to the actual % drain. System battery displays 15% of usage (with 'full device usage' on show) when the battery is quite evidently at 48% from full charge. Total cluster****. So pissed off I updated.
Have you seen any improvement in yours with any of these workarounds?

Nothing to lose by trying. And as I said, Greenify makes it easy/quick to do. Force closing is almost as good as uninstalling those apps as the vast majority of installed apps won't restart or run in background until you use them for the first time again. In my experience, quiescent battery consumption (e.g. noticed over night):
Is vastly affected negatively by poor cellular signal strength. Marginal coverage can really drain the battery fast.
Gradually gets worse between reboots
Can be improved (once it degrades) if you force close all the apps you've installed, and swipe away the background apps just before you go to bed!
If quiescent consumption suddenly rises I can normally fix it by force closing all the apps (not being sure which was the one gone rogue/suddenly misbehaving)
At night I generally have excellent cellular coverage, good WiFi, and Bluetooth is off. NFC is always off
I don't enable sync on 2 of the 3 Gmail accounts I have configured
I disable notifications from any apps I don't actually need them from
Quiescent battery consumption is between, say, 0.4% and, 0.7%/hr at home, around 2 to 3%/hr when out and about which I put down to all background data being driven over 4G instead of Wifi, and variable cellular coverage
I've not noticed quiescent battery consumption change between Oreo and Pie, but this may be because I keep force closing apps at night and not giving adaptive battery (which I have on) a chance to have the same effect intelligently
Turning off app preview messages has made no practical different for me
I'm completely stock (stock launcher, not rooted, etc.)
If you can't fix it, at least a factory reset as the next experiment has the option to restore *most* of what was there before (so long as you have had the backup setting enabled). But because not everything is restored it's still a pain. And if that doesn't work it's another factory reset and test and then restore everything manually and gradually :-S. But I think you already tried that?

Thanks, just tried that as well and my battery has stayed resolutely at 68% on idle beside me for the last few hours, previously it had gone from 100% down to 69% in about 4 hours whilst similarly doing nothing.
