So i recently bought the galaxy s7 and noticed that my battery drains faster than it should. it also gets quite warm most of the time. i tried a ton of fixes that didnt help and was wondering if anyone can help or has the same problem. i did find out that snapchat was overheating my phone and taking up a lot of battery but even when i shut that down it still seems to drain fairly fast. would be great if i could get some help on this. thanks
Charge it to 100%, use it until it completely depletes the battery. Charge again to 100%. Deplete. Do this for the whole week. This is recommended for any new smartphone battery.
I just bought two S7 Edges. All apps, etc, are configured the same. It's been a week now, and one phone is at 40% at the end of the day while the other is almost dead. The 40% one went through the 100-0% procedure since the day it came out of the box. That's a huge difference. It does work.
As for the heat, I can't say. Neither one of the one's I have overheat.
The S7 has a tiny copper heatpipe inside that wicks the heat to the metal frame of the phone. It's especially noticeable whole charging. From all accounts this is normal.
As for battery life, mine was awesome until I received the April ATT over the air update.

Thought I would create this to see if you're happy with the battery life on your Vox and post some tips about charging and discharging for better life.
I am generally dis-satisfied with battery life on the Vox however I keep a fully charged battery in my Jeep, one in my wallet and one in my Vox to always stay connected. I switch to my 2250mAh when I know I'm doing to be using WiFi a lot.
Anyways, here is what I have found;
If you reboot your phone while charging, it will jump to a higher charged state and not properly store the charge. To combat this, I have placed a strip of electrical tape over the 2nd connector to the left on the battery which stops the battery from reporting the proper charge level. I run it down and place it on my external charger. Charges last a lot longer after I do this.
Any tips for how you use your Vox to maximize battery life?
I am happy, because I usually get through one day without any problems and then I am plugging it in over night anyway! I'd love a battery with higher capacity, but I hate those extended covers!
I'm happy with the battery life.
I find it lasts longer if I use the phone until the battery is pretty much dead and then charged until full again.
I usually get 3-4 days out of it that way.

I am not happy at all. 3-4 days ? I bought vox few days back and I get 2 days max, with most of time on standby.
Okay so I received my 2250mAh battery cover, finally. However when using the battery, my device shuts off randomly, this only happens with the extended battery. It also seems the contact sheets are deeper and the pins have a hard time reaching them. If I slide the Vox shut hard, it will also reboot.
Any idea's?
The battery life is fine as long as you don't OC it. I manage to get 3 days with normal use.
With the CPU up to 240Mhz, it barely lasts a day. So i rather use the original 6.0 rom without OC and its still fast. WM6.1 is to slow without OC'ing for me.
So after 6 months of use i finaly found my settings wich i like. And makes the battery life OK for me

I got this too when I just received the battery, but after something like 2 weeks these problems disappeared
I'm happy with battery life...
I get up to 2 days with heavy voice, email, and text -- some bluetooth, very little WiFi or Internet. Personally, I've never had a problem with a phone as long as I get a full day and can charge at night. Even if I got 6 days on a battery, I don't want to have to remember to plug my phone in at some point during the day when the battery is about to go. Much easier to plug in every night.
Battery life is exceptional!
I was having problems with my original battery; the phone would simply power down even though it showed that it was charged; and did not have long battery life.
I bought a new battery now I get 3 even 4 days of use with some Bluetooth and WiFi use (not much though). The new battery also seems to have solved my power down problem; had it for 4 weeks, not one power down. I am using the LeFab VoxRomWM6.1XIP20202_v1.0. Quite fast on it's own; I do not over clock.
Hi all,
I have a Samsung Galaxy S2 from work, have had it since summer. Got the Sensation XE for private recently and been having a feeling it's consuming the battery well faster. After making some searches and reading some I purchased one of those Anker 1900mAh batteries, got it yesterday and charged it up. I then had both phones lying on the table, screen off doing nothing. About 2-3h later the Samsung was at 98% whilst the HTC was at 87%!!!
I decided to at least restart the HTC and after the restart it showed 88%. I then left them over night, more or less 8 hours - right now the Samsung is at 90% and the HTC at 74%.
Now I know that batteries don't reach their top performance immediately but require a couple of charges first, but how do these numbers sound to you guys? The 13% drop within the first 2-3h was scary and ridiculous, but the overnight loss seems reasonable yet still far worse than the S2. And this is with the Anker battery, not the original.... the Samsung is rated at 1650mAh only.
I've not done this test with the original battery yet, it seems that it kept it's charge better than the Anker though - although on the other hand it had a tendency of staying at 100% for quite a while then dropping faster. Is there some procedure to calibrate/reset battery perhaps?
Cheers

You could let the battery of XE die and recharge it back to 100% for a few times. If you are rooted be sure to clear battery stats first when you battery is fully charged before doing the above procedure.
Somehow i've been getting rather great battery life with Anker. Probably only losing around 5% when left overnight. Did you clear battery stats when trying out Anker? That may be the reason why the battery life seems poorer as compared to Galaxy S2.

Hi m8,
cheers for the reply - I do not currently have the phone rooted and, as a matter of fact, would like to keep it that way. Was looking into the wipe battery stats/resets but all I did find related to rooted phones. Guess there's no way for a non-rooted?
It's currently down to 32%, the Samsung is at 70%. That said the HTC has had some light use whereas the Samsung has been sat in my pocket all day, doing not much more than pushing work email and some syncing.
Was thinking to plug it into charger now but better to wait till it's nearly dead? Or even till it shuts itself off?
Sense is a resource hog so that is where probably the majority of your power is going, take a look in the phones battery settings
Had it on charge over night (phone switched off), unplugged it around 7 this morning, so approx 7 hours ago. It's now at 92% with some light use, which is quite impressive - if it's "true" (I'm expecting that battery level is going to drop much faster during the day than it did this morning, when it was at 100% quite long).
Right now it's showing:
34% Screen
34% Phone idle
18% Phone inactive
10% Phonecalls
4% Camera
Not sure that's actually since last charge though, as I've no recollection of using camera at all :/
*edit*
whilst posting this and having screen active it dropped to 90%... so let's see how it is going to hold up during the day...
Hey all,
I am currently running CM9 (bhundven's 7-29 herring build) on my Galaxy S 4G, and I am having some problems with random shutdown. This has only been happening for the past few days or so (EDIT: and I have been running CM9 for about three months with no issues). It seems that the phone works perfectly fine until the charge gets to about 60% starting from a full charge, and then the phone randomly shuts off. The phone will not start back up unless I have it plugged into the wall, and the results are a little unpredictable. The first time it happened, I turned it back on and it said the battery was at 1% and charging. Now, after clearing the battery stats, it reboots to 60% battery. It seems to work perfectly fine after that, and yesterday it went all the way down to about 12% before I started charging it again. It just happened again today, and when I turned it back on it said it was at about 60%.
My charging habits are pretty bad for Li-Ion batteries; I tend to let the charge drop all the way to about 10% or 5% before I plug it in and charge it all night, way past what is necessary to get to 100%.
The battery does look a tad swollen, but I might be exaggerating.
I just wanted to know if this is a bad battery with 100% certainty, or could it be a problem with the OS or internal parts, etc. I can easily buy another battery online, and I probably will.
EDIT: Also, I have had some overheating issues with this phone, and I can often smell electrical smoke in the charger port area behind the speaker, which is why I say it might be an internal parts issue.
Thanks everyone,

You need a new battery. I was having the same issue lime 3 months ago; phone was dying at half charge the when it rebooted, battery would be dead. Then when I plugged it in, it would charge in 20 minutes and the repeat the cycle. Put the battery on a table to see if its still flat. If it rocks or spins excessively, its usually an indicator of a bad cell.
Mine JUST started doing the exact same thing last week. Battery is definitely swollen. I replaced it just this evening and I'm in the process of doing a full charge from 0->100 to see how things go. I'm 99.999% sure the battery was dead. Replace yours.
Sorry for the thread necro, but I wanted to thank the OP for asking this question and to the helpful replies. We just had a heat wave here and maybe coincidentally to that, I've been having random shutdown problems. Having looked at this thread and my battery, I can tell that I definitely need to replace that. So thanks, all!
I have a lot of trouble with the battery on my S7. Shortly after updating to LOS 18.1, it started behaving very strangely. The battery degradation happened over a couple of weeks, so it rapidly got worse.
At the beginning it shut down at anywhere between 15 and 20 percent, most of the time with the 15% warning. It got worse over time, then at some point it switched to being stuck at 80+ percent for almost the whole day, draining very little battery and then it just went black in the evening, like if the battery was pulled out.
I started slow charging the battery, which made things a bit better again. Now the percentage seems to be somewhat accurate again, but battery is draining so fast, I have to charge it twice a day to keep it running. It even drains battery while off, like yesterday I turned it off at 35% and this morning I couldn't even turn it on. Sometimes it also jumps from 100% to 60% after a reboot.
I made a backup and tried resetting the system, which didn't work, same behaviour. I could try to go back to stock, but as it also drains battery while off, I'm not too confident that it will actually make a difference.
As I have another disassembled S7 still in my repair drawer, I could try to change the battery, but my glass is a bit shattered at the bottom of the touch screen, so I'm afraid I'll completely break it this way.
I don't think there is much I can actually do, but I wanted to ask you people for any advice.
Edit: I have successfully transplanted the battery from my other S7 and it works great again. No battery problems at all, so the culprit was a faulty battery.
Hey there,
I bought a couple of devices to repair and among them was a Galaxy S6. It had a very bad battery life, so I bought a new battery, put it in and reset the cycle counter. The battery life is better now but not okay.
What I found then was, it drains battery while off. And not like a couple of % a day, more like 5-6% an hour. When I compared temperatures, I noticed that the device is not hot, but it's noticeably warmer than another S6 I have around still, like lukewarm. Opening it up again, I tried to find the hot spot and looking at the ifixit teardown, it looks like the PMIC (the blue one) is the culprit - see here. I'm not sure if there is anything I can do about it. I tried cleaning it to make sure there is no shorts around but that didn't seem to help. I will try a hot air gun later today to see if that fixes anything. Any other ideas on what I could try to locate the issue?
Cheers
