I love my G2 which up until a few weeks ago has had incredible battery life. The phone is a D801 (tmobile) which has been running stock Lollipop (5.0.2) since I bought it. It appears that my Bluetooth has been taking up most of my battery. I don't recall it ever doing that prior to the recent battery drain. I have cleared out the Bluetooth cache and data, but it hasn't seemed to helped. I couldn't find any indication of a system update during this time. Any ideas, besides turning the bluetooth off when I don't need it?

I had the nexus 4 for few months, and has been the best phone I ever had.
I had only a small issue when my battery started to consume faster than usual, my business email went in loop so I just reinstalled it and everything was fine.
Problems started last week: I decide to buy a Samsung S4 (I really need the wifi calling, and I would like to remove and switch the battery),
so I go to tmobile and sign for it. They give me a new sim and transfer my old number on the new sim.
I did not install app, nothing else changed. From that moment Battery is draining super fast (will not last over 3 or 4 hours now) Has problems also to charge (I don't know if it's for the charging or becuase is draining the battery so fast)
I have also problem with wifi now, also if as usual I will connect to my home wifi, datas will not work.
Now that I have the wifi off, is continuing to drain battery very fast.
I rooted the phone as soon as I bought it, I'm still on 4.2.1
Tonight when I will receive the samsung I will unroot the phone and will update to the new version and will do a factory reset, hopefully the problems will be solved
Is possible that the battery drain and the wifi problem are caused simply by the new sim?
Has anyone had issues with really bad battery drain on newest update?

I haven't noticed a drop in battery life after upgrading from CM10.2 to stock 4.4.2.
I have very few apps on my phone and I keep wifi and data off when I'm not using my phone.

It was my GPS eating up my battery. Mixed with the weather channel app. My battery was dead in 7 hrs.

Bad Battery Life
Hi
Yes, I have noticed a dramatic drop in battery life. I use to get home from work about 6pm with about 50% battery life. Now by 2pm I'm less than 10%.
No Bluetooth. No GPS. No NFC (this was originally on when getting to 6pm). WiFi on. WiFi Off. Doesn't matter. Turned location services to battery save or off. No new apps.
I have converted runtime to ART (worth having a read up on this), which can potentially give up to 20-30% better battery.
The funny thing is at home with full WiFi and strong 3G reception the battery life is exceptional! 2-3 days standby (light/medium use). The 3G reception at work.
A friend suggested that possibly the radio (3G) isn't locking on to a specific tower and keeps bouncing between towers chewing up the battery.
I will try a factory reset and see if it fixes the problem. From what I've been able to discover online it doesn't seem to be a very common problem.
Same Here
My girlfriend is having the same problem with battery drain.
GPS is off and she's using Wi-Fi at home.
When Google rolled Kit Kat OTAs I had to wipe her phone and flash the official Mako factory images to actually get it updated. So the phone isn't rooted and It's completely stock now. The 4.4.2 OTA update installed just fine. Then she noticed the poor battery life. Android system and Android OS are the 2 highest battery users in the list (will try to get a screenshot of this later)
Is the factory reset working for any one?
Has a reinstall of the factory images fixed this?
Any other suggestions?
Just wanted to ask everyone before I spent a bunch of time on it.
Thanks so much!
factory reset doesn't resolve
I did a factory reset and the issue still exists. I have removed 1/3 of my apps, 80% of the photos on my phone. I tried running Bluetooth off 100% of the time. Turned off location reporting. Turned off syncing any Google service I wan't using. None of these helped. My problem is intermittent. I will make a change then go a couple of days thinking "problem solved," then on the third day massive battery drain reoccurs. I think the battery monitor in the OS is unreliable when this occurs becasue it will report an app like "Flixter" as the main source of the drain. The next time it will be mediaserver, or TV Guide.

You got a lot of apps it sounds like. My problem has been eliminated sense removing weather channel app. Been good for two weeks

Same problem.
I have read millions of forums and this problem is not going away. I also have intermittent battery drain - it works for a few days and then everything goes back to sh-it. I've tried everything - deleting apps, turning off all services i don't use, power saving mode, sync, GPS, and nothing works.

Thanks for that note! I know my gf uses the weather channel app. Will tell her to remove it.
On a similar note. Now a few months later now and her battery wont hold a charge for more than 2 hours and wont charge to 100% every time. Her phone is only a year old. luckily she called google 2 days before the 1 year warranty was up. They sent instructions on safe mode and some other tips. Hopefully she'll end up with a new battery and i'll make sure shes not using weather channel haha.
Huge battery drain when tablet is "sleeping" - probably because "bluesleep"
Hello,
I have problem on my N7 with large battery drain.
I had this issue witch Stock ROM, now I tried to root stock ROM (4.4.4) and install Greenify, but battery still dies after 2 days of no usage.
I tried to charge it fully, reboot it, cleared cache and dalvik cache, and put it to "sleep". After one night, 40% of battery was gone.
It seems that my N7 is not going to "deep sleep" for some reason.
So I tried to install numerous of apps to find what app is responsible for this. None was successfull, until I tried BBS.
In attachment, you can find BBS dumpfile. But it seems, there is some "bluesleep" kernel wakelock, which is responsible for all my troubles. Unfortunatelly, I dont know what this process is. Or am I reading dumpfile wrong and some other app/process is responsible for this huge battery drain?
I also attached screenshot from standard android battery statictics, which shows, that "Android OS" is preventing tablet from sleep.
Is there some way to fix this issue? Tablet worked normally for 1.5 year, but in last months is unusable, because it has dead battery everytime I want to use it.
Thanks for advices.
I would imagine bluesleep wakelock is related to bluetooth. Do you have BT on and/or connected to anything using BT?
If so try turning it off and see if it persists.
Yes, I use Bluetooth for my Jawbone UP24 sync. But I have this band only for a week. Extreme battery drain already was there before I have got UP24. In these times I had bluetooth turned off all time. So I dont think this is main reason.
I turned off BT. Lets see what happens in the morning.
UPDATE: You were right. It is bluetooth. When I turn it off, tablet is most time in deep sleep.
So probably rooting and installing greenify worked, but in meantime, I started using UP24 and Bluetooth on tablet.
I will try if situation is better with some AOSP based ROM. I did not wanted to flash another rom (than Stock), but I guess, there is no other way. Even clean Android on Nexus device is not usable with comfort...
I received and installed the 5.1.1. update to my Canadian Note 4 last week. Immediately I noticed the battery was draining faster and clearing the cache did nothing so I bit the bullet and did a factory reset. That has not fixed the battery problem.
My Bluetooth seems to be the main culprit as it drains the battery constantly even when not connected to a Bluetooth device. I use it to connect to my vehicle so I do not want to have to turn it off and on manually.
This was never a problem on my S3 running 4.0 to 4.2 or my Note 4 from 4.4 to 5.0.1. Bluetooth never drained the battery on those OS's and I do not want to be told to manually turn it off when I don't need it. I'm hoping someone has or had a similar issue and knows how to fix it.
This is a stock unrooted Canadian Note 4
Thanks.
Anyhoo, after some arduous googling, I found that the Gasbuddy app has been giving some people the same bluetooth wakelock issues I've been having. I uninstalled Gasbuddy a couple of hours ago and the problem is gone.
Here's the page in case anyone is interested:
https://code.google.com/p/android/issues/detail?can=2&start=0&num=100&q=&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars&groupby=&sort=&id=87778
After updating from Lollipop to Marshmallow (stock UK firmware), battery life was absolutely terrible. With most of Google and Samsung apps disabled along with wifi, GPS, bluetooth and just light usage (1 hour of browsing and whats app, 30 mins calls), the phone would barely last 10 hours. Taking it off full charge at 8am and by 5pm it'd be around 20%. Whilst using the phone, I'd lose 1% every four minutes.
I tried a factory reset, wipe cache partition and everything else you can think of. GSam Battery Monitor Pro showed nothing was killing the battery and there were no rogue apps. The same SIM in my S4 mini running KitKat with the same usage easily manages a day and often far more.
I was going to flash down to KitKat and if this didn't work, sell the phone, I was that sick and tired of it.
Then I tried disabling 4G and leaving it on 3G only.
Bingo!
Battery life MASSIVELY increased. With the same usage, I'm now easily able to manage 2 days. My S4 Mini doesn't have this problem so I can only assume the problem is with the radio part of the Marshmallow firmware. I live in an area with poor reception but all my other phones on the same network have the same weak signal and none of those have battery drain.
Onto the lag then. Since upgrading to Marshmallow, the whole phone felt sluggish. Scrolling was jerky, the lock screen would take a few moments to show and even the smart manager always said I had less than 300MB free of RAM. About a week after upgrading though the phone suddenly restarted itself and upon boot said "Android is Starting - Optimizing App x of xxx". Once this had finished, the whole phone was snappy again and RAM was back up to over 800MB being available.
Bit concerned why the phone restarted itself but happy with the much improved battery life and performance so far. Will give it another week before deciding if a downgrade to KitKat is still necessary or might just sell the phone.
So if you have an S5 Mini with serious battery drain, try disabling 4G.
Well thanks for that, I was skeptical but I gave it a try. I booted in recovery mode, wiped dalvik cache and once optimization is done after reboot the phone was quite snappy. I've not tested battery life on 3G only mode yet.
According to Samsung Galaxy S5 Manual- guideusermanual.com/product-name-galaxy-s5-manual&po=356337&lang=English following guidelines are suggested by experts to fix battery drain:
Stop unnecessary apps.
Replace your old battery with a new one.
Your charger does not work.
'Android system' using too much battery.
Google Play Services battery drain.
Switch off auto-brightness.
Shorten your screen timeout.
Watch out for widgets and background apps.
Well thats unexpected
Coming here after I just got my new s5 and I gotta say this works like a charm. I disabled the 4g and I'm getting huge improvements. IAM on factory's Tom ty for this.
Just disabled 4G and I think it makes an impact, a good one. S5 G900F here.
I have S5 G900F with official stock Rom along with Marshmallow 6.0.1 update and IT DRIVES ME CRAZY!
The phone is usually EXTREMELY slow and sluggish. I cannot smoothly navigate and scroll around the apps, and I can NOT wake the phone up from lock screen instantly. Even waking up from lock screen takes ages. It is very laggy. I tried everthing and not working.
I beleive either Marshmallow kernel has a nasty Cpu bug or Samsung intentionally slows down the phobe just like Apple does.
I hate it.
What are your thoughts?
