So t-mobile sent me a brand new MT4G a few weeks ago, I sent them my HTC G2. I like the phone and it has been great but just recently I've been experiencing battery drain and I've noticed that the battery temperature increased a lot. The phone started lagging a bit as well.
I downloaded OS Monitor to see if any apps were causing this. I went through the list all apps were at 0%. However, I did notice that the CPU usage is always around 92-98%. And the very first process is titled "/init" and uses anywhere from 80-94% load. I clicked on the details and here's what it looks like:
Process: /init
Memory: 256k Threads: 1 Load: 92%
STime:277132 Utime: 424258
User:root Status: Running
Could that be the issue?
Not sure what else to check.
Any help would be greatly appreciated.
Just wondering what rom are you using? Did you flash OC daemon?
Wow you must be living under a rock.
There are reports everywhere stating that T-Mobile is having a problem with their 4G network. Some people are falling victim to their battery draining grasp. While others are frolicking through the fields with no worries.
Android and me has reported it, there are several threads on it, T-Mo News is reporting it. T-Mobile's support forums has acknowledged the problem.... it's not really hidden at all.
Originally on my N4 I was rocking straight talk ATT side, my battery life was awesome... Well then I recently switched to T-Mobile monthly 4G (faster speeds) and now even after a couple factory wipes my battery doesn't seem very good. I check what's consuming and Android OS and android system is always in the top 2. I can't seem to get those two programs to calm down. Its not a rogue app, I don't have any apps besides xda installed. I am not rooted just running stock. Has anyone else seen a battery life drop since using T-Mobile, is it that significant? Any advice or tip would be appreciative.
This is really interesting to me. I've read a great deal about the Nexus 4 battery issues but as far as I know they've never been linked to carrier. Of course, I haven't read everything about it and someone might have made a connection along the way, but I haven't come across it.
Do you use the Better Battery Stats app? If so, check the number of msm_hsic_host wakelocks. On a good day, mine hovers around 10-12% of the overall wakelocks (today it's 22%, who knows why). To my knowledge, this is related to the Android OS in the stock battery analysis. I'm on AT&T. This would make me hesitant to jump to T-Mobile when my contract ends in March. Hopefully 4.2.2 fixes the problems regardless, but has anyone else seen worse battery life on T-Mobile than AT&T?
My G2 used to last forever but now the battery drains really quickly.
For example, doing something a simple as reading through posts on here for 2 minutes sees the battery drop about 3%.
As you can imagine, I can't really do too much without killing it within a few hours.
The 3000 mAh battery was a huge selling point when deciding to buy last year, but now I'm not so sure it was the right decision.
I have the D802 model from Taiwan, but using in the UK.
Using the phone in Taiwan, I get LTE /4G without a problem.
In the UK depending on the network, 4g is enabled automatically, however on my current network (Three) I have to go into the secret menu to get 4g to work, afterwhich, if the phone is reboots for whoever reason, then it is reset to 3g.
Im not rooted, running stock rom.
Any ideas? Typing this message has dropped me from 85% to 8²%
Hello guys!.It's my first time here. So, I have some questions regarding this problem
I bought my S7E around july, and it had amazing battery life, It lasted around 30hours++ but I drained the battery by playing games so I can charge my phone before 5pm(my office hours) to avoid over charging when I go to bed. I even used the best perfomance that time, gps on, gestures on, etc.But still at least it lasted for 27hours.Now, it only lasts for about 12 hours something. Ive never overcharged it. The moment I saw the green led, i plugged off the charger.
Can anyone fix this? well please don't tell me to turn off all the features, I had them on and still I got to use 27hours. I dont know when I did the update, maybe os 6.0.1 is draining the battery?or any suggestion?
Thank you
Go to Settings>Battery and view the usage to see what app is using it much battery.
You can NOT overcharge the battery of your S7 Edge. I've always kept my phones on the charger over night and never had problems. I'm doing that since the HTC Magic (T-Mobile G1). It has overcharge protection. It is NOT good to drain a Lithium-Ion battery down to a few %. A Lithium-Ion battery operates the best when charged >40% and at average room temperature.

Nope. I never drain my battery.I keep my battery until 20% then charge it directly. I know how to take care of Lion battery. Ive heard about the overcharging protection feature but i'm not sure whether it works.we never know whether that program runs on background or not since we cant track it.

Well, then don't charge overnight. You're problem is most likely software related anyway unless your battery is very old and/or you overstressed the battery too often which can't be because the S7 Edge isn't that old and you "...know how to take care of Lion battery". I think you meant Li-Ion but w/e. A defective battery is possible but very unlikely. BTW overcharge protection is not a program. It's a physical thing soldered onto the battery/charger PCB. Hardware. There's one built into the battery and one inside the charger and of course we can track it. You can't because you probably don't have the equipment + knowledge to test it. If you're so concerned, you should really read about it. After all, you're dealing with a highly reactive metal.

Well that's why i charge my phone at my office:crying:
i wonder if the OS is the problem. I've heard about drivers not compatible on s7 using 6.0.1 so the background data keeps working such as gear vr service. It wasnt there before. and OM Customize. So, if i overstressed my battery, it will damage my battery? I did that before to charge my phone between morning to evening.

You're hearing really weird things buddy The S7 Edge has always been running Android 6.x.x. It never ran any other Android version. The drivers are fully compatible. In fact, the drivers on a Samsung are as compatible as drivers can get, since SoC, Camera Sensor and many other parts of the phone are coming from the same manufacturer; Samsung.
My guess, and I can only guess since we'd have to see your battery stats for more detailed explanations, is that you either ran into the Android System-, or Google Play Services battery drain bug that occurs after an OTA update. These problems date back all the way back to the Galaxy S2.
I'd recommend you first flash a stock ROM using the "HOME_CSC" file. This will NOT wipe anything from your phone. Only the core system and stuff will be reinstalled. If you still have this problem, try flashing a stock firmware using the regular "CSC" file. Always make a backup first. The regular CSC file will WIPE EVERYTHING from your phone, including internal storage but it won't touch you MicroSD. Now you start with a freshly installed Android and see if it solved your problem.

Hello mate,I am sorry for my late reply since I gave up. I am trying to solve this again.
Well, can you tell me where can i get the stock firmware? I am from Indonesia(well I think some parts of the continents have different firmware).I wanted to flash it tho but I am afraid I got some "hacked" firmware.
well,the battery usage looks normal to me.
google play services around 5-15%
android OS 15-20%
android system 15-20%
but still,it drains too much>,<
Let me try to upload a pict of it.
Additional information : Slept 8 hours while listening to music and it drained from 55% to 2%.I mean this is really insane.That's why I am taking serious action now. The first time I bought it with the same settings and apps + I turned on always on display and night clock while listening to the music for 8 hours of sleeping,it only drains 10-20%.
I took this ss because I got 30hours on time : link
these are the drained ones.15Nov and 9 Dec
15Nov
9Dec
Thank you mate
First out of all. How much SOT (Screen On Time) do You get?
To check that go to battery usage at the end of the day or when You have 20% and in battery usage tap on screen and take a screenshot.
Second.
Certain firmware updates decrease battery life a little.
And third.
You can disable apps that are draining Your battery if You don't need them.
Also for a really good battery info what uses Your battery etc You can download GSAM battery monitor from play store.

well from the time being, i think my network operator is draining my battery.I tried to turn off my mobile network last night and used wifi instead.I lost 1% for 8 hours.Well, I changed my network operator around october and since then I felt the battery drain. I already sent report to the provider hope they solve it.
But I wonder, my network operator has good 4g coverage here, why does it drain too much? My old operator had only 3g coverage.Is there any way for me to track down my operator whether they are using too much battery to search network coverage maybe?
Newest firmware always decrease battery life a little
I'm using a sprint galaxy s4 on ting, and while I'm 'okay enough' with the phone to not want to futz with upgrading, one thing that's made me reconsider is that I notice really fast (like 30% over an hour sitting in my pocket) battery drain when I'm in an area with low cellular signal. Particularly there's a coffee shop back section I sit at where this happens. My battery is also years old, but it's worked okay at home in standby.
Any idea if there's a baseband version I can switch to or things to observe to see if this is fixable? Using stock 5.0.1 rom with L720VPUGPI2 baseband.
Wont let me comment
Have you heard anything on this? My brother has same issue and also wants to root but i cant find anything on this build #
