Hello to all. This had been something I noticed for a while, but only took into consideration when I found out the tab 2 7.0 's battery capacity. For a while I've been getting on average 3 1/2 hours battery life. For a tablet with a 4000mAh battery, this concerns me. So is this battery life expected or may there be something underlying?
Any help appreciated.
Depending on the age of the tablet the battery could be exhausted and need replacing, or you may have apps chewing up your battery life.
Install CPU spy from the Play store and monitor over a 24hr period, you may have a better idea of what's going on.

OK thanks so much. Appreciate the reply
Flash AA kernel by android andi
Battery life might decrease for a various reasons. How frequent do you charge?
If you never had a moment where you didn't charge it for days, then the battery might be fine and problem lies with some code. It might be a calibration problem due to a bad recovery version. With less dev support, the bug may have gone unnoticed in the recovery.
Try this: Fully discharge your battery, even after it shows 0%, restart continuously till the tab doesn't start(not even recovery). Keep it like that for an hour. Then attach charger and charge till 100%. Again keep it aside for an hour after full charge, with charger disconnected. Then turn it on and check.
The FG chip does 2 measurements at 0 and 100% after an hour idle and recalibrates. A shortcut is go to a repair shop and open the back cover and disconnect the battery for 20mins and then recalibration will take place instantly. Don't trust the calibration apps in playstore, they're meaningless.
If it still doesn't work battery,kernel is to blame.
It is because of the kernel. The kernel of CM is not good at saving power but the performance is not bad at all.
However, I found that the AA kernel by android andi or Dhollmen kernel version 3.0.101 (http://forum.xda-developers.com/showthread.php?t=2176563),
these two are both really good at power saving and powerful.
For me, I would prefer Dhollmen one because the installation is sample, it just flash the file at the recovery mode.
Hope these information could help.

Hi folks - this is the first thread I have started, hence requesting the non-noobs to go easy on me... (this forum is a scary-kind-of-cool)
I mustered up the courage to install Infused 1.5.0 on my stock... the instructions were superb and everything went great... really enjoying the improved speed and looks. But my battery life has degraded. It has been more than a week since I flashed my phone - and it is only getting worse. Now I have read a lot about how Infused is getting great battery life for some folks... and i have gone through those threads, trying to figure out what I am doing wrong. This is my typical usage profile
1) I put the phone on charging before I go to sleep... when I wake up (around 7 AM) it is fully charged.
2) I quickly check overnight messages, finish the daily ablutions, and 30 min later when I check the phone it is already at 95%.
3) By 10 AM, I have made a few long phone calls (no bluetooth) (totalling 60-90 minutes) - and the battery is down to 75%
4) At work I use a bluetooth A2DP headset - maybe 30-40 min of calls and by 12 I am at 50%.
5) More calls in the afternoon, intermitted mail checking and sometimes 30-40 minutes of music streaming on my bluetooth headset - and by 6 PM my phone is down to critical level 12-15%.
This is in now way the same experience that others are having with the Infused ROM and with the Infuse phone in general.
Other points:
6) I run Juice Defender... (don't know if it helps)
7) My screen brightness is just a few notches over 0%
8) My data is always on - except when I am using Wifi of course
9) I turn bluetooth off when I am not using it
So that's the story guys... and I would eternally grateful if the awesome folks out here can help me figure out what I am doing wrong... or there is some logic behind the sad battery life of what is otherwise the best phone that I have ever owned.
It depends how long Infused has been running on your system. After about 3 days I noticed my phone was adjusting to the ROM and the battery life improved significantly. Aside from that, try this trick. Drain your battery next to nothing and then charge all the way. Do this a couple of times. Not quite sure about the logistics but it seems to work. Another thing that has improved my battery life is to make sure I don't have background apps running. You can check this by going into apps > manage apps > and then running. Sometimes Media Hub will begin a background process and that eats up a whopping 8 MBs alone. Force close these pointless background apps and you should see an improvement there as well.
have you conditioned the battery and reset battery stats?

Thanks popesmasseuse (you really aren't are you?)... the ROM has been running now for a week... gets worse rather than better. I do typically wait for my battery to drain completely before I charge it... but when I do have to do it at 7 PM - then I can never charge it fully, before I have to start using it again. I wonder if the fact that my phone goes through "micro charges" is a reason for my declining battery life...
Will check the running apps... and see if closing them improves things... thanks!
Fact: Installing a ROM greatly improves battery life... Try it....
Turn of GPS and Bluetooth when not in use.
Same here I uninstalled media hub... period... just useless...
Phone calls are a pretty heavy battery drain. Sounds like you're in call for hours each day. Most people don't talk on the phone more than a few minutes a day. Poor signal will also significantly reduce your battery life... how many bars you usually have at work?
My battery life got better the longer I had the infused ROM. But personally I only talk on the phone maybe a total of an hour each day, but I am constantly using internet and youtube, and if I have spare time I'm using my Kindle app to read some books. I keep my GPS, sync, and wifi on all day long and my brightness all the way up (I just can't stand a dim screen lol) and by the time I got home today my battery was at 40%, which I am perfectly fine with.

Ah...the man himself.
Yes I talk a lot on the phone - nature of the job. 3 hours minimum in a day. Signal at home is terrible - 15% strength... that could be the reason why the battery runs dry after the morning routine. Any way to offset that?
At work signal is great. But in office I also tend to use my desk phone more...

Read the thread in my sig.
Never use task killers.
For me, battery life on phones gets good after about 2 weeks or so.
With light to medium use I can easily go for 2+ days.
Consider not streaming music through Bluetooth. Also don't auto sync stuff every 15 mins. If you can use Gmail they use Push notification. I'm on my phone all day literally and I make it home with some battery left. BTW connect to a Wi-Fi when ever possible, 3g data streaming will kill your battery quick.

It's a Lithium-Ion battery which means it does NOT respond to "conditioning".
"Reconditioning a battery involves completely discharging the energy from a battery then recharging the
battery. Li-Ion batteries do not require reconditioning to maintain good battery performance since Li-Ion
does not have a memory effect. It is necessary to complete drain and then recharge a Li-Ion battery in
order to determine its current capacity level, but that is not the same thing as reconditioning the battery. Li-
Ion batteries do not have a condition that needs to be reconditioned." lxe.com

Keiht's tutorial is effectively a technique called "bump charging" for putting that last extra percent or two of charge into a battery. However - with Li-Ion batteries, charging like this will SEVERELY reduce their charge cycle lifetime.
The only thing that "calibration" should affect is how your device reports battery charge level, NOT actual power usage. You should get the same total battery life whether your device is "calibrated" or not, with the exception possibly of the device shutting off prematurely because it thinks the battery is lower than it really is.

I would have to agree with you. I followed his directions as i was having horrible battery issues after going to 1.5.0 and it seems to have helped the reporting as far as I can tell. I think the big problem and it is only a guess is how the phone is reporting the battery condition not actual battery left. In any event I am running JD and the longer I run with 1.5.0 the battery seems to be lasting a lot longer but I have ti disable most everything which hobbles the phones best features to get that battery life still searching for the perfect solution.
Hi guys
I have a galaxy s2 and im having problems with the battery. In the battery usage section the most that takes up the energy from the battery is the display. Even lowering the brightness settings the display is still sky high. Now having flashed it few times the warranty has now gone. Tried different roms and still the display on my galaxy is like 45 to 55 percent. Some say its normal some say its not. Once i fully charge the phone within minutes the battery starts getting drained. Seriously what is wrong with it and what can i do to resolve it. Im past my month that i could send the phone back and samsung obviously will find out its been tampered with ie me flashing it
Is there anything i can do to solve the problem with firmware or am i stuck with a faulty phone and just make the most of it till something else comes along?
Any help or ideas will be appreciated

The battery might be dying. How old is the battery? Li-ion batteries will work for 3 years or so only regardless of whether you used it or not.
The display might be taking up so much battery because that's how you use the phone. ie you don't use much of other battery heavy stuff. Make sure you have a low timeout for battery as well.

The display battery usage will be relative to how much screen on time you have. If you are having problems with how long your battery lasts, download BetterBatteryStats (from my sig) and run it for 24 hours or so then check the wake locks to see if any rogue apps are draining your battery.
If you want to return the phone. You can always flash the stock rom and if you buy a USB jig from ebay, you can reset the counter, so Sammy shouldn't know that you have flashed any roms.
For further tips about your battery, why not look at some of the custom rom threads, like Villainrom. They have very good battery stats and there are plenty of tips in the thread.
Hope this helps
well i have it charging at the moment and i am using cognition rom and the phone is like sleeping as we saying. i quickly went into battery usage and display is like 85 %.
Shall i charge it to the max calibrate it then wipe battery stats and let it drain out till its empty fully charge it and then use it till the end of the week and then post a picture of how it went for you guys to see and you give me your ideas on it?
thanks again i really appreciate your opinions
I have never bothered calibrating my Battstats, but it makes some people feel better.
As I said above, the percentage used by display is relative.
If your phone has been on for 24 hours since charge and your display is 85%, then you have a major problem, as your screen on time must be massive.
However if it is 10 minutes since charge and the display is 85% then that probably equates to a few minutes screen on time.
Once you are charged. Run the phone for as long as possible then post screenshots of the Battery Usage (both pages)

Agreed with killall. Battery stats are relative. Say you have used your for ten minutes after charging and the screen was on for 5 minutes or more, an 85% for display is nothing big.
Like he said, see the overall performance of the battery and its life. Display percentage doesn't make that much of a difference if you use your display a lot. I mean if you don't do much CPU intensive gaming or stay connected to wifi and stuff.
Battery drainage has been a major frustration for me with my phone. The frustration stems from the many variables associated with battery drainage. For the most part the terrible battery drainage started after flashing the modified ROMs. I believe the stock ROM was respectable when it came to battery drainage.
I am not ignorant to flashing ROMs. I have tried everything to figure out this battery problem; everything to keeping stock kernals, to battery calibration (delete battery stats), to battery bump charging, to matching radio files with RILs, to limiting data syncing, charge cycles etc.
But I am noticing that some of you are able to get good battery usage from a single charge with these modified ROMs. With that said, I want to cut the variables down and see what those folks who are getting over a day's worth of battery usage from a single charge are doing. The best indicator for battery usage to limit variables would be the battery usage standby rate with data network on.
I am not getting any better than 8%/hour on standby for any of these ROMs. That is crap. I wake up in the morning after 8 hours and there is only ~35% battery left. Unacceptable. I figure no more than 10% should be lost in 8 hours of standby.
So for those who have good battery usage, please answer the following questions so that we can eliminate all the variables.
1. What is your standby battery drainage rate?
2. What version phone do you have (TMoUS or EUR)?
3. Clockwork Recovery version?
4. What ROM are you using?
4. What Radio and RILs are you using?
5. How many charge cycles are you doing after the battery calibration and before you are getting the good standby rate?
6. Are you using any battery saving applications?
Please help if you can. Everyone seems to emphasize speed and performance but battery life is number one priority for any phone in my opinion.
Thanks
I'm currently running the P3D Neon ROM. I was having the same issues you are having due to flashing a new ROM jsut about every day. The big thing I noticed is that the longer I stayed with the one ROM the better my battery was. But as I'm sure you already know that no matter what a smartphone is a battery hog anyway.
By the way have you tried this, I am using it and love it !

More than likely, there are apps that are not allowing the phone to sleep when the screen is off. CPUstats will show you how long your phone has been in deep sleep, as well as your CPU clock speed.
Here is what I would try out:
1-Get CPUstats.
2-Turn off the screen for the night
3-Check to see how long the phone was in deep sleep mode. It should have been for awhile if not, you have a rogue app that is bothering your phone while it sleeps.
To check your standby current:
So far, we cannot accurately see what it is. I dont know of any app that can for our phones. I do know that the values I see cannot be correct, otherwise my phone wouldnt be lasting long.
1-Write down your current battery capacity in mA/Hrs.
2-Write down the time that you put your phone into sleep.
3-Leave it off for an hour.
4-Wake it up and check the new battery capacity.
An Example:
I started with 1900mA/Hr.
I let it sleep for 1 hour.
I found that after an hour, I was down to 1850mA/Hr. That is 50mA gone, over 1 hour time. So my standby current was 50mA/Hrs.
Now this is only a crude way of judging whether or not your phone is behaving. Since the battery apps update capacity every 5 mins or so, you may not be right on the money, but you WILL know if something is BAD. Calculating 50mA +/- 20mA means the phone is likely sleeping as it should. Calculating 300mA+/- 20mA means something is USING your phone without your permission.
Youll need to find out if some apps are syncing (or trying to sync) while it sleeps. Or, your phone may be trying to improve your signal strength.

The anker battery will help but it is not solving the problem. We need to be getting around 1-2%/hour standby drain like some of you guys are getting.

I like this test, I will check it out.
Hello everybody!
My HTC Sensation is acting kind of weird the last few weeks.
It all began when i flashed CM 9 on it. It worked great, but pressing both the volume button would cause it to crash, so i flashed CM10 (kang) to it.
Now what happened at CM9 already was that it would just turn itself off at some points. During browsing, or taking a picture, Or just sitting in my pocket.
I had a almost full battery at that time(about 70%+) and it just went dead, reboot would give me 1% left. In CM10 the same problem happens. This time i took screenshots of the battery management screen, i included them in the attachments.
I wiped battery stats even tough it is a myth but could always try it. Did not fixed this.
Now the funny thing is when i reboot the device and it says it has only 25% left of charge. It reboots and BAM i have 75%, Reboot it once more and i lost 10%, rebooted again and it kind of stabilized. Now i have it on the charger and i am watching it, the LED on top stays on orange for about 2 seconds, then turns to screen for 1 second and then it turns of. then it just cycles trough the same again.
I hope i am making myself a bit clear about this and i will answer all questions i might have left out that are important.
Please help me because i cannot trust this phone anymore, it dies without warning and i have to boot it to find myself stranded with 1% left (which ironically can last for hours if the phone doesn't die).
PS. I included 3 screenshots. The first 2 are from when it died 2 times, as you can see the dips.
The last one is when i rebooted it and it gained allot of percentage.
Thanks in advanced

Have you checked to see it if you have any wake locks? You can check with better battery stats apk. Also might be time for a new battery. You can get a good extended battery like anker for under 20 dollars,. My stock battery life was so bad, changed it to extended battery now it's really made a difference!
Hi,
I recommend you to see if you have any wakeclocks (Check via BetterBatteryStats)
You might have a bad flash. Check MD5 of ROM/Kernel
Check your running applications.
Let your newly installed ROM settle down for a few battery cycles.
But in your case, maybe a new battery?
I moved before few days from stock ROM to Bruces CM10 from 14.11. and have battery problems too. It drains to fast ROM is pretty stable, but with this battery life, I can hardly use it... Now I am on battery only for 10h 26min, display was ON for only 1h 55min and I am on 17% with battery... Something is bad

Hello,
I've searching for like 2 months about problems with battery life and Lollipop with nexus 5. I understand the issues but since it was released, i never had much problems with it. I used to have 2h SOT for like 40% battery or so.
My daily routine allowed me to reach home with a bit more than 50% battery with 2h SOT more or less. (a lot of messaging on viber/whatsapp)
But something changed since 1 and half months ago. I can no longer do the same and it seems that i have a CONSTANT battery drain. I remember when i unplugged my phone i would reach my workplace (1:30h after unplug) i would have like 2-4% less battery depending on the usage. Currently when i get out of home the battery is already at like 92% or more depending on the usage. If i let the phone stay idle all the time, i usally get home with 30-40% battery now. I'm already thinking that my battery has gone bad. This started to happen from one day to another and i never let the battery stay too much below 30% usually, but nowadays it's impossible to predict the battery life since some days it seems to drain more than others.
I've used some apps to monitor the usage but i really don't understand much about it and can't seem to find a pattern. I've already did factory reset with all Lollipop versions and i remember doing a KK regression for some hours but the drain seemed like it was still there (can't use KK on my nexus 5 anyway, it feels weird after Lollipop experience ) but i didn't even fully charged the battery as i remember. Anyway if it would be an app, there should be some kind of logging in battery stats which doesn't, and i can't think about anything else.
I finally gave up and decided to ask help here, since i don't know what else to do. I'm actually leaning towards getting a nexus 6 but after reading about so many issues (screen/battery life/burn-in) i'm not sure what else i can do with my nexus 5.
If anyone can give me a hint i'd be very grateful
PS: already tried Cataclysm ROM and using currently ElementalX kernel. I notice a bit better battery life with ElementalX but i think the pictures speak for themselves.
Judging by that constant drain with very little shown awake time I'd install Better Battery Stats and check for kernel wakelocks. I had a similar situation with a wake lock from using a wireless charger that did not show in the regular battery stats.

i already installed it before, but currently don't have it installed. I have Wakelock Detector app i can post a screenshot if helps
Installed Better Battery Stats, i'll post results tomorrow (battery at 19% already).
As promised, there's still some battery left but i didn't even use the phone today mostly... in days like these i should be over 70% as usual or maybe close to 80% that i remember.
Can't seem to find the cause
bump i guess
will some full discharge cycles fix this ? iirc that can make things worse.
I feel your pain...when I was on Kitkat, I'd get to work running just Waze and Pandora and my battery life would be at 80%. Installed Lollipop 5.1 and now half way through my trip (15 minutes of use) the phone shuts down with a dead battery. Maybe it's just a coincidence that my battery decided to give up the ghost at the same time I install 5.1, but I find that very odd...the phone is only a 1.5 years old...lithium battery's tend to last 2+ years and even then they don't fall off a cliff in terms of capacity. At this point I think I'll buy a new battery and see what happens, LG OEM are about $25 on Amazon.
