Battery life after root (tab 4 10.1) - Galaxy Tab 4 Q&A, Help & Troubleshooting

I decided to root my tab 4 with odin, it was a fast root and had no problems at all, thing is, after rooting the battery life is really bad, with the charger connected it says 80% and after i disconnect it it goes to 11% next minute 0% and shuts down... i charged it all niht and only charged 47% also, i read a book with low brightness and the charger plugged and the tab charges, but now even with the lowest brihtness it just starts depleting the battery... is there any fix? The cwm recovery that comes for this version does not have the option to erase the battery stats thingy....any ideas?

Look in Play Store for a Battery Calibration. If that doesn't solve your problem then maybe the battery is f***ed up.

Well first, it's not a cwm recovery. But my nitpicking aside, try a battery calibration app, try also allowing the battery to fully drain, and give it a few fresh charge cycles
Also have you looked at the battery usage screen to see if it says whats draining it?

I have same problem. I try to use Battery celebrator and delele batterystat but not work

Evo Battery with 1.47 OTA Massive FAIL!

Since applying the 1.47... OTA, I can literally watch the battery drop minute by minute while the phoe is active.
Within the first 1 minute of removing the phone from the charger the Battery Status Pro reports the charge droping from 100% to 97%. That's a 3% drop in 60 seconds.
Within the first 3 minutes of active use BSP reports the battery drops to 93% charge. That's 7% loss in less than 200 seconds of use.
Now I'm not saying BSP is 100% accuerate but I expect it's not too far off.
Battery life with the Evo has never been phenominal but this seems rather extreem. The drop seems far faster now than when running the 1.32 release. And... while I am in a 4G enabled market, this is with 4G disabled and the phone running purely on 3G with no flickr, twiter, facebook or other feed widgets running and autosync disabled for all of them.
When I look at Battery Use under settings / About Phone / Battery the Android System is by far the largest user of battery, nearly twice the next closest user which is Cell standby.
Am I the only person experiencing this?
The phone was doing this before the 1.47 OTA, it's a problem with charging the battery in the phone. It does not charge properly for some reason and it will drop all the way down into the 80's within an hour of unplugging it. If you get an external battery charger and use it to charge the battery the phone will stay on 100% for an hour or more...
Have you removed the HTC people widget from home screen? The day I removed that was the beginning of decent battery life. Also try turning off the phone when charging - seems to work better that way.
I would try charging to 100%, unplug, wipe the battery, plug it back in again until the light turns green and try again and report back.

I wondered if it was the powered off portion of that battery trick that was doing it. Hmmm. I'll have to watch. Is there any link/source on the idea that the phone itself is not working so well at charging?
Out of that voodoo on the getting better battery life the only thing I could come up with was...-charges better when off, - you need to charge for a bit while on to reset the battery indicator, - and charge a bit while off to top it up.
So I was leaning toward it being a charging thing and not a battery thing...would like to see any technicals though and not just my guessing.
People widget has been long gone.
I gave the charge it with the phone powered off thing a try. The device was down around 80% charged when I powered it off and plugged it in. In about 5 minutes the charge indicator turned from amber to green as if it were fully charged.
I can't believe that the battery charged 20% in 5 minutes.
This leads me to believe that the first response is correct. The battery simply isn't charging fully in the phone. I believe I'll look for an external battery charger and give it a try. See if it makes a difference.

Seriously, try full-charge, wiping your battery data and then shutting it off and 'topping it off' and reevaluate the situation.
EDIT: The "topping it off" thing is all voo-doo as far as I'm concerned. I just do it to be safe, though I'm pretty sure it's ineffective.
I screw with my phone so much, so much flashing/restoring back and forth while on charge, between
charge, car charger, USB charge at work, wall charge, flashing again, kernel swap, restore back again...etc etc etc...that if I don't wipe my battery once I hit a full charge there is no way I can trust that meter to do anything more than change colors. I do it every few days when I notice the meter isn't being trustworthy.
If this doesn't work for you I'd say you probably have a bunk cell in your battery, and failing that your phone just might not be charging well.
Also, charge with the wall and not USB. USB takes forever. And 20% in 5 minutes isn't TOO far off if you are plugged into the wall and getting full-power charge. Maybe 10-12ish minutes, unless you were timing it very specifically....
I just got my bricked replacement. Here is the data from a 100% charged battery usage up time 18:13 .. Awake time 15:27 the battery is at 87%
funny im getting 20 + hours a charge after the OTA
with heavy usage

[Q] Wipe the battery stats am I interpreting this right?

I have allready read:
Battery recalibration (Thanks to Cyanogen for this and to fachadick for bringing it to my attention).
If you're experiencing higher than normal battery drain, try the following:
1. Charge the phone to full battery; let it keep charging until the battery says it is fully charged. Do not just wait until the light is green, it isn't always fully charged, causing a lot of inaccuracies. (You can check by going to: Settings -> About Phone -> Status -> Battery Level = Full.)
2. Boot to recovery and wipe battery stats.
(To have the most accurate of battery stats, reboot the phone immediately after wiping the battery stats and wait for your ROM to boot completely to the desktop. Once your entire boot is done and you have full access to the phone, go ahead and pull the charger and continue.)
3. Do not charge the phone until after draining the battery completely, resulting in it automatically shutting off. Take out the battery, and keep trying to turn on your phone until it will not turn back on at all.
4. Recharge the phone completely and then use as you normally would.
This is a method that has been proven to work, I am sure there are other ways. My battery lasts longer after doing this and the reading is much more accurate. It might be advisable to do this after every ROM install if you want the most battery life and most accurate battery reading by the phone's software.

My question is dose the phone need to be off or on for stage 4 the recharging of the battery?
If it can be off for stage 4. Dose it need to be charged in one sitting or can I charge it partially then take it to work and then charge it the rest of the way before I turn the phone back on?
This my second attempt at doing a battery stats wipe. The first time I tried I left the phone on wile charging and the battery only charged to 3800mV calming it was at 100%. I had to bump charge it 3 times over 3 hours before the battery was up to 4100mV-4200mV and clmaing 100% charge capacity.
Evo 4g Ur3 Stock root Seidio 3500mAh extended life battery.
1) You can have it on
2) NO! charge it from 0-100% in one sitting
I did it according to the above with my 1&2 and im getting accurate readings now as well as the battery life i should have.

I wonder if this means that I will not be able to have proper battery stats as my phone likes to stop charging and claim that it's at 100% when its actually at 50-80%/ (It dose this 95% of the time... It even did it with the stock battery stock battery a couple of times)

Simplest way to calibrate your Battery [for root users only]

I noticed that in CWM 3 (on gingerbread running device), when u click on wipe battery stats in CWM, Nothing happens while in old CWM's when we use to click on wipe battery stats, we get a message "battery stats wiped successfully".
So to wipe my battery stats, i found a software in android market called "battery calibration"
Just download this software from market (its free) and you will get your results.
https://market.android.com/details?id=com.nema.batterycalibration&feature=search_result
I plugged in the cable to get to 100% charge (4250mV), I clicked "Battery Calibration" then waited until it was done and unplugged the phone. Then it was at 99% wtf. What does this mean? Is my battery calibrated now or what?
Multiple posts on here full battery reads 100-97%
Battery is only calibrated after battery stats wiped battery drained and charged to 100% then phone used for two weeks .

Thanks for the info, man. So, now that I have calibrated with this app, I just have to drain the battery to 0% - then the phone turns off automatically - and recharge till 100%, then it's calibrated? Woah
PS: Do i have to recharge my phone while it is on or better while it is off?
Galaxy S 2.2.1 firmwares never show 100% battery life when not on charger. As soon as u unplug ur charger the level will drop to 96% or something. Reconnect ur phone to charger again and after 5 mins it ll again show 100% than again as soon as u unplug it, the level drop down to anywhere more than 96%.
just untick wait for 100% option in battery calibration software and ur battery ll be calibrated. do once ur phone is fully charged and once when ur battery level is just 1-2%
Actually its down to the modem version you run.
I ran one modem version that gave me excellent battery life (near on two days of constant use and only 50% drain. Also it STAYED at 100% for about 20 minutes after unplugging if i didnt use the phone, when i used this modem.
The problem is that to get better battery life you have to compromise on signal quality on the modem. The less battery the modem uses usually results in less signal strength, because its not using as much power to find its mast.
read #11 in "Getting the most out of your SGS" thread. That section is on why it's not good to overcharge your battery.
11. Do NOT overcharge
--Why, when, where: Almost all new batteries have an overcharging protection. This means that the protection that is built into the battery will not let it charge to 100%. This is a feature, not a bug! This will help prolong your battery life while also keeping it safe from overheating/explosion/etc. Do not try to trick it and unplug and plug again until you see 100%, just get used to the fact that you can't have 100% battery anymore and live with it, or you risk destroying your battery.
My device only goes upto 4170mV.
Anybody has the same issue?

Broken battery?

Hi!
I'm suffering from a strange battery behavior lately: This morning, after 9 hours charging, I woke up to a 75% full battery, when usually, it should get 100% charge overnight. Previously, I had an accidental power off by power depletion, some hours ago.
Now, I'm trying to charge the phone but it seems to charge way too slow.
Finally, I decided to power it off and let it charge without any possible drainage. In the moment I powered it off, I was prompted with the battery icon displaying 96% charged...??!?!?!?
I don't know if either the battery is broken, the rom is reporting it wrong or what.
I usually play Ingress, which drains the battery like crazy, and I'm usually browsing the internet and reading twitter on my phone, so, at the beginning I thought I just needed to keep my hands off the phone for a while and let it charge, but after that overnigt 75% charge incident... I don't know what to think.
ROM is Carbon ROM KK, kernel is AK without any tweaks, no undervolting or anything... any advice?

Don't over charge.
Yes, I have the bad habit of being unable to see my phone drop the battery level under 60%. At my job, I always leave it on a qi charger, regardless of it being full or empty. Perhaps I have to take the habit of letting it drain until 30% or so, and start charging then.
Other thing I can do is limit the charge level top, tweaking the kernel setting via synapse..... Could that be a good thing?
After starting the phone, the battery level seems to be OK. It's 87% now and it's draining quite slow, compared to before. I guess I'll have to start treating my battery better.

Some update: the phone was bought on March 2013,but the battery has a build date of December 2013. I think the guys that repaired the phone swapped the battery for another one and left me with a defective one.

My S7 Edge G935v battery drain so Fast at 15% - turn off suddenly at 5%?

Hi,
My S7 Edge G935v runing Lastest G935U Firmware QG1
My battery drain from 100%-15%...normally, but from 15% to 0% drain very fast. (5%/time: 15-10%-5%). and when 5% remaining it turn off suddenly.
My screen on about 4.5-5hous...
So Should I replace new battery? and how to fix or calibrate battery?
In my opinion the battery is ok

Before I paid for a new battery Id probably factory reset and see if it continues. Id also install accubattery from playstore. Youve got to let the app measure your battery health for 24 hours. Itll tell you how much battery capacity you have left (degradation)
But based on your observations, I'm not sure you need a new battery. Do you always let it run so low?

Battery Health in accubattery now is 96% after some charge times
15% remaining about 5mins using
hello,
I'm Italian.
Same problem for me since a week for my S7.
But I done the last update few monts ago (Android Nougat).
What we have to do?
Try an app called Advanced Repair Battery Life. You can find it on Play Store:
https://play.google.com/store/apps/details?id=com.mocamocaapps.advancedbatteryliferepair
Once installed, open the app and hit 'repair' and wait until the process is finished. Once finished, reboot your phone and see what happens.
I've used on my father's Sony device and it seems to work.
hello, an update.
without factory reset, without app.
On Monday, the battery is crashed from 14% to 1% in few seconds. Then a notification prompted me to correct the anomalous consumption of an app (it was whatsapp). I correct it and the it is remained turned on for 2 hour and half (without using) at 1%. Then it goes in auto turn off. Then I turned on and I wait that it goes in auto turn off. Then I plugged and I loaded battery to 100%. I think this procedure is called calibration.
The next days battery is not crashed, it has normal consumaption.
Today I will monitor what will happen.
thanks
Hi guys!
I got the same battery issues here.
Noted 2 days ago, it was at 15% remaining, talked 1 minute with my colleague and the S7 was turned off. Tried to turn it on, the battery was 0%, plugged in and recharged for a while.
Yesterday the same, at 15% turned off, then I monitored it and around 5/7% it switches off on its own.
From 15 to 5/7% goes very fast, in 1/2 minutes and not more. In this situation on the right side it becomes very hot.
I experienced a similar situation with my Galaxy Tab S, the screen was flickering and overheating issues with looping reboots. Solved by an unplug/replug of the internal battery.
I'm very worried about my S7E!
Just for note, I use Quick Charge very often and a magnetic support for car use.

Yesterday evening the same on my device. Spotify prompted as anomalous consumption, corrected and the drain stopped for a while.
Opened Tapatalk and here we go again with the fast running out. Hope that will be better right now.
Installed accubattery app, my battery has 72% of health.
