Battery Life Issue - Galaxy Tab 3 Q&A, Help & Troubleshooting

Hey everyone.
I have galaxy tab T210 and I was using nolekat's rom. I install the boost pack after that, in order to maximize the performance of the tablet.
I messed a bit with the cpu frequency but I did set it back on the stock. A couple of weeks later I saw that I had battery issue, more specific the tablet would go off after a 10 minute video on youtube in full battery capacity and would remain on 1% for a long long time. I tried changing in a couple of different roms but in every rom the battery would have the same behavior.
If there's someone that had the same issue or can at least provide some help that would be amazing

[Q] Huge Drop in Battery Life after 2.17 Update

Hi all,
My battery life on the One X has been great before the 2.17 update. Better than the average being reported on this forum.
After 2.17 it plummeted to 14 hours or so with barely 2 hours of screen time.
Nothing was changed after the update on my end. Same apps, etc. All on stock.
What are my options? Will a hard reset solve it?
Thanks.
Update
The factory reset did the trick. Battery is back functioning properly and I did get extra juice out of the 2.17 update.
If you do find a weird drop in battery life and the ONLY change is that you updated the firmware, a hard reset may solve it like it did for me.

You should go thru a couple of charging cycles before complaining about battery time.. everytime you flash a new rom or update the phone the battery has to calibrate ( as far as i know ), and that takes about 2 - 4 recharge cycles..
in case you already done that, then check you sync settings, brightness if its too high, or low.. Maybe you are used to be on wifi instead of 3g ?
It has gone through over 10 full charge cycles.
Sync is off. Brightness minimum.
Wifi and 3G usage patterns are similar.
Just noticed that Phone Idle is consuming a lot more.
Maybe it's the new radio which is affecting your signal, try flashing an older radio. My battery life is better on the new firmware.

i first of all found the battery life had dropped, i ended up resetting the phone and it got much better, i think some old app was getting lodged in the memory and preventing deep sleep.
i ran it for about 2 weeks before i decided to wipe.
@nikzDHD
I suspect it could be that. My provider does not provide that strong a connectivity. But that is something I can't change for the next year or so.
@audiobookman
I decided to wipe it today. Also waited about 2-3 weeks before deciding enough is enough.
--
I did a HTC Battery test and found that my battery was in good condition and performed way better than their baseline. So, I went on to wipe the phone clean and started from scratch.
It was not a painful process actually. Most of my stuff are on the cloud (Google/Dropbox/Skydrive) and the only things I had to back up was the list of apps I had and some settings from apps like Tasker and Minimalist Text. I got everything back up and running within an hour + (reinstalling 60+ apps and getting them setup the way they were takes time).
So far, battery seems a lot better and back to the former period but, it is too early to tell. I'll give it a week of use and a fair amount of full charge cycles before commenting.
Will update this thread then.
If anyone has other ideas please sound out. Thanks a lot!

I do a factory reset after every OTA because of the reasons you mention of this thread. After it battery life seems to get better or at least not worse as on previous firmware version. I hate doing that but it seems the only way

Power-saving optimizations and results

My girlfriend just got a P6 and asked me for advice on battery-saving and I have noted there is no thread on power-saving optimizations and actual results so I have started one.
Can you please post your battery-related results and any optimization that you have done about this?!
What firmware?
How much battery discharge do you see over day?
Even more relevant - how much battery discharge do you see over night?

Newest firmware is meant to be good, also theres a few power saving options in the menus, some users have reported that they get up to 2 days moderate use

Thank you for your feedback and I hope others will provide info too (and ideally some numbers).
Just to place things into perspective and show the kind of numbers that are most relevant for such a thread - my i9300 over night has a battery discharge of around 2% over 8 hours (that is registered on the voice network so that I can get voice calls but with WiFi off and data off; most apps are also set to only update on WiFi or manually anyway). In order to achieve that I use a custom kernel, power-saving enabled on a Samsung-derived ROM with root and then Titanium Backup to freeze anything that I use less than once/week and Greenify for almost everything else.
I plan on trying some of the above on my girlfriend's phone next weekend or the one after that, and until then I was interested to learn more about the subject.

I also have a samsung galaxy S3 Gt-i9300 and have rather moderate battery life, last night i lost 20% ! I have the Boeffla kernel, which do you use?
Huawei are meant to be good at this sort of thing, im getting real tired of only having a phone capable of 2-3.5 hours of screen on time ( S3, Nexus 4 ) So, im hoping the huawei can deliver that or ill be going to something with a bigger battery ( Nexus 5 and underclock it too 1.5ghz maybe less to save some major battery life )
I also would like to see what users are getting in terms of numbers, screen on time would be great

Currently I am mostly using Googy-Max, but over weekends I normally do a lot of experimenting and for instance last night I noted an increase from 2% to 4% (over 8 hours), which could be from moving from Googy-Max 1.7.5 to 1.7.6 or from moving from modem EMF1 to EMG4 - for the moment I moved back to Googy-Max 1.7.5 and I will see over the next night if it was the kernel, the modem or both. Also as a note - I get about 4-5 hours of screen time, but with low use and I "adapt" the brightness (I have some profiles defined with LLAMA and I keep the brightness on lowest auto when I am indoor and only go to max when I go outdoors for more than a few minutes).
That being said 20% is extreme - I have only seen such numbers in CM 10.2 (where it is said that there is a bug that prevents the modem from sleeping after a cellphone call, but the last word is that it might now be fixed). Either way on i9300 it is a well-known situation that Sammy ROMs (after some degree of de-bloating) still are a huge lot better with power-saving than CM. Which was the kind of info I was looking here about the Ascend P6

Do you reccomend Googy-max then? All i care about is batter life!

I am still answering here since I believe what I am about to say could also be very relevant for the P6.
The thing is that in my experience the kernel is only relevant for battery life once every single other problem was fixed!
In other words if the over-night (8h or so) battery drain is 20% then your gains from the kernel will not be very relevant (and technically Boeffla and Googy-Max are not very far apart in this regard). If you are on a CM 10.2 (or 10.1?) the main advantage that I see is that Googy-Max will let you keep that (I suggest to move it to secondary) and then install a de-bloated Sammy as primary and then see for a few weeks how is battery life between the two.
And another thing that could be also relevant to the P6 - on my phone I am replacing the "stock" launcher and 'stock" dialer with something that for me is a lot snappier (but that remains to be seen if it will be well-received by my girlfriend on her P6 - or if it will improve anything).
But generally BetterBatteryStats and Greenify tend to improve battery life (sometimes a lot), so it looks very likely that I will have to root that P6.

Ive got to hand it to you, i had a good look on the googy kernel and found many, many battery optimizations and found threads to do with underclocking, undervolting and other tweaks and the batter life is amazing, im only running it at 800mhz and its really smooth and fast still, so thanks for introducing it to me, its made my galaxy S3 a whole lot better.
Although there is one bug, ill turn on phone, connect the WiFi, turn the screen off and it will disable the WiFi :S im on 1.7.5 and have asked if 1.7.6 will fix it, fingers crossed

Chronic battery issues with a variety of ROM's

Hi,
I've searched through various threads here and in the development/ROM forums but need some advice and didn't find advice for my specific scenario.
From Jan - Sept this year I was rooted but running the stock 4.1 Android (Rogers), I tried CM10 and a few other custom ROM's but eventually went back to stock carrier TW, with the only root change being the 4.2 Camera (for Photosphere) being installed (via CMW). During that time my device ran pretty ok in terms of battery life.
Then in Sept I started getting serious battery drain issues. I've got a few extra batteries and an external battery charger so I ended up swaping in and out charged batteries twice or three times a day.
So I decided to re-enter the root world and have since tried a variety of ROM's to see if the battery issues might be fixed. Installed TWN recovery rather than CWM, Tried ROM's such as Task650, CM10 Stable, CM10 Daily, and I still am encountering pretty dismal battery life?
I've tried various battery apps and generally keep screen brightness to a minumum, turn off mobile data, and have wifi/gps/bluetooth/sync off for most the day
I can't imagine it's the battery themselves, 1 is the original that came with my GS3 last year, 1 is official Samsung bought a few months ago and two are Anker ones that worked fine for months.
Can anyone recommend a specific ROM that may have worked for you? I haven't really messed around with custom kernals much, only played with kernals and governors a while back when trying out SETCPU (which I havent used in ages).
Any ideas?
Thank You.
Try the app BetterBatteryStats and see what is using up the battery. After a few hours of having the phone idle, look up the process running on the phone that uses the most wake locks.
Hi,
BBS did not really reveal one glaring thing draining the battery while the screen was off.
Any other ideas?

1 road : 2 destinations

I know that its irritating for the pros out here to see a question regarding a BEST ROM. But I am not asking such a question.
I would like the most battery friendly rom for my n7100 runnning stock 4.3 now. The 4.3 has ruined my battery life and I am looking for a way out. I would love to get the single handed operation in all windows from note 3 also.
So once more these two are what I am hunting for:
BEST BATTERY BACKUP
[*]SINGLE HANDED OPERATION IN ALL WINDOWS (NOTE 3 FEATURE)
Hope I am specific here. Could you please suggest me the ideal ROM solution for my situation..
I never could understand people claiming that a certain ROM is better concerning battery than the other. OK, ie. if you have Note 3 apps there might be some SLIGHT difference, but this is all nothing compared to the REAL drain caused by the screen and DATA. It also depends what software you use - you could have best battery friendyl ROM but if you install stuff that wakes the phone and consumes the battery - it won't matter. Also depends how you use your phone i.e. if you play 3D games ofcourse your battery will last shorter tme than if you just make phonecalls. When you use "light" ROMs, with much bloatware removed - battery will be a little bit better but you will lose functionality. But all of this is sooooo little that it hardly matters.
On 4.3, as on 4.1.2 - my battery lasts like 16 hours and then is down to 50%, and then I'm in panic to charge. But I just went abroad and turned off my data because of the roaming costs. And guess what? I had my phone on for 2 days, 1 hour screen on time and the battery was at 60%.
So no ROM will save you if you have A) data on B) screen on. You're welcome to do some tests. But try without ANY installed applications or with SAME apps installed, keeping screen on time same. And you'll see it makes no difference at all or minimal difference at best.

Battery Life AFTER Lollipop Updaate

has anyone else seen a dramatic decrease in battery life after the update? My battery went from lasting all day, to now Im lucky to get 5 hrs before its down to 30%..... overall ive seen a drastic decrease in overall performance... has anyone else expierenced worse performance?

keep calm and factory reset. That should fix the stability and battery life.

No better no worse, my battery life has always been great. Example today, unplugged at 7 am , no recharges during the day and it's at 55%.
I used the phone , surfed and checked my texts and email all day

You are not alone. I used to be able to go a couple of days on a single charge. Now I'm struggling to make it 12 hours on a single charge.
I was getting almost 2 days when I first started using the note4. After a few months passed I noticed battery life dropping pretty fast throughout the day. Factory resets helped a little, but not much. Lollipop upgrade plus factory reset has seemed to help. I get through a full day now with light browsing/gps(maps)/gaming and fair amount of spotify streaming. Nothing close to what I was getting fresh out of the box.
I am experiencing similar battery issues. Used to charge my phone once every two days. Now, I carry my charger attached to my hip like a feeble iPhone hipster.
I'm also having issues!
I also have seen a large decrease in my battery life since updating to Lollipop. I tried factory resetting twice and nothing seems to help. I was getting 8-9 hours of screen on time on Android 4.4.4 but now I'm somewhere between 4.5-5.5.
Also my note 4 will occasionally get really hot after just normal web browsing. I'm very disappointed in the update. However, performance seems to be a little better....but it wasn't ever really an issue.
I just read an article on gsmarena about the international version of the Samsung galaxy note 4 receiving a firmware update.....hopefully that fixes the problems we're having. We just have to wait for Verizon to send out the update. (Which will probably take a couple of weeks to months).
One thing to keep in mind is that we (those who are having these issues) need to make sure that we contact Verizon in order to make sure that they acknowledge the problem and send out a fix ASAP.
I'm having the same issues since the update...battery sucks. What's the easiest way to inform verizon?
Passpoint Wi-Fi
Noticed that there is a "new" Passpoint Wi-Fi feature that will automatically connect to certified access points.
This is ON by default after the Lollipop update. (Settings >> Wi-Fi >> Advanced)
I just turned it off to see if battery life improves. Never been a fan of automatic Wi-Fi connection features.
Checking on the Lock Screen Weather/Location Update next.
My Note 4 has the battery drain issue now after updating last night to Lollipop but am giving a couple days to see if any improvement. I did do a battery pull after all the updates (system and apps) and it did seem to help.
My Note originally for a couple of days had the battery drain issue. However, after uninstalling the Google Fit app then a reboot the battery life has been great.
Maybe try a battery pull for 20 seconds as well.

I think the easiest way to contact Verizon is just by talking with the technical support. Good representatives are hit or miss but Verizon's are generally good.
If you contact them just explain the issue that you are having and they should be putting it on record saying that multiple people are calling in concerning a battery problem. They may have even figured out the culprit (s) and/or found a fIx.
I'm going to be calling today.
