Hey, I have the SM-G850F on 5.0.2. I just rooted it to fix some problem I've been experiencing:
Bad Reception:
The signal strength shows -95 dbm 9asu, usually 2 or 3 bars. I don't mind that, the speed of internet and quality of calls are ok. The problem is that it randomly cuts off calls with no reason or change in location. It's an recurring problem. Happens a lot to different callers. Some people say that when they call me it beeps as occupied while I know for sure that I wasn't and I don't even get an alert of missing a call.
Bad battery drain:
Without any battery apps the phone drains from 100% to 30% in one night, completely untouched. I don't have more than 4 pages worth of apps. Avast battery app saves a lot of battery turning wifi on and off everytime i unlock it and it doesn't find homewifi. Greenify has prolonged the battery to satisfaction too, but then I got a new problem.
Lagging menus!
It's a second way too long. I'm not being whiney, it really is slower than it should be or even was stock, 4.2 something.
How can I setup this rooted phone for optimal experience? I'm 100% noob.
Should i look into custom OS (Roms?)? How can that help me?
How long battery time should i expect out of this phone if i set it up properly and how do i do that? Is there a less battery taxing way than avast battery app?
Is there a way to test this call cut of reception thingy? Should it be included under warranty? should i unroot my phone and turn it in?
What other root apps are essential for optimal alpha usage?

So I'm on stock 4.0.3 now (kernel 3.0.15-I9100XXLPQ). Everything was fine right after the update. But a few days later my phone started to use more battery than it had used: I'd used to have around 60-65% of battery after coming to home from school, but a few days after the update I had like 40%. Also, sometimes I was not getting incoming calls and text messages, despite the fact that the signal bar (sorry, I don't know how you call it in English) was full.
I looked through the threads on xda forums and one guy suggested cleaning the micro USB port. His theory actually made sense for me, so I cleaned my micro USB port. I also installed CPU Spy to check if the phone uses the deep sleep mode.
Today I woke up and after 4 hours I got 91% of battery life. 'Hell yeah, problem solved', I thought. But suddenly the battery drain started again. I asked my friend to call me. He couldn't, because apparently I had no signal, but the signal bar had also been full.
Look at the screenshot. '1' is where the battery started leaking. '2' is where I rebooted my phone. After the reboot everything is fine, but I think this problem will appear again shortly.
These battery drains and losing the signal are really annoying, one night the battery dropped from 50% to 30% in 2 hours without even touching the phone (with WiFi, data transfer, GPS and Bluetooth off). What causes these problems? Can it be related with this bug in ICS?
The thing is that even Samsung hasnt been able to do a proper release as GB. GB stock rom had quite a solid battery life...Many people have seen massive battery drains and in most of the roms phone doesnt go into deep sleep. Hence causing of a lot of battery consumption.Id suggest not to use stock samsung rom and shift to a custom rom or downgrading to GB. I myself have read a lot of threads with the same problem that you are having.
I'll shift to CM9 as soon as these issues with recording and watching videos will be solved.
I can understand the battery drain, but I completely don't know why there's a problem with the signal. It's not that my phone doesn't go to the deep sleep at all. It just glitches at a certain time and the battery leaks and the signal is "lost".
I'll check tommorow if the phone really doesn't go into the deep sleep when the battery is leaking and nobody can call to me.
Bump, because the problem with the signal is really annoying.
I am thinking that its possible that all these poor battery and ICS posts are maybe that the users have not flashed firmware for the phone but rather generic stock some other providers firmware .
As i said only a thought as the majority are not direct firmware updates .
I would be running Better Battery Stats to find the drain anyway .

It's been two or three days since I did the factory reset. Now I'd say that battery got better, but the problem with the signal still occurs.
Which mobile operator are you with?
Plus GSM, I'm from Poland, my Galaxy S II is the international version of course.
Okay, I've installed CM9 on my phone, but this problem still occurs (altough now the screen uses much less battery, due to CM9's better brightness managing).
I'll explain it once again, because now I can describe my problem more accurately:
SGS II shows that I have signal, however, I can't receive calls and text messages. While it's happening, the battery life is dropping a lot faster. By "a lot" I mean 5% in 10-30 minutes when I'm not doing anything at all.
This started happening a few days after update to ICS. What should I do now? Install a modem from GB?
Yes start experimenting with older modems i would look to the last working GB modem you had .
Also some are reporting the later ICS is better than earlier releases .
jje
How do I find out what version of modem I had before?
I get about 7 hours of battery everyday through medium usage and my battery drains quite a lot when I am revising and listening to music. I have a 1900 battery instead of the stock 1650 and it does improve battery life but is there anything else I can do? I find it a bit stupid that my battery drains so much when I'm just listening to music!
I am running CM9.
Whats the signal strength like in your area? Aside from the screen (put screen brightness down), 3g seems to drain my battery most in weak signal areas, where the signal bars are continuously on 1 or 0. I put my 3g / data off and my phone can easily go hours before any drop in battery percentage, I got 4 days battery life with 3g off using it sparingly or wifi when i could to check my emails. Only other thing i did was calls and texts, but that was just as a test.
But i like to keep data on, and gps, all the time. I often get 4 hours screen time and approx 24 hours battery life with my 2000mAh Samsung battery.
Aside from that, last time i checked cm9 was a battery drain, may have moved on a bit.
the only real way you can save battery "during use" is with some restraint. Ie turn brightness down if screen is on, listen at lower volumes if it's playing music. The more voltage it's using the faster it drains. So less brightness or volume output = less power used.
7 hours is around the average use for battery life savy users around here. Even with the extended battery I'd say your right about on the money for battery use (based on what I assume you do and don't know at this stage). But there is certainly room for improvement .
Now before I go on, you probably won't notice any significant difference to battery life during use from these steps. My only hope is that in-between use it'll save more power, and squeeze out a bit more usage time for you.
First/easiest thing would be go to check if it's sleeping properly. Just don't use it for say an hour, then go to the battery monitor in settings. Check the screen on and awake times, they should be almost idenical. If there are several awake records in between screen on's, then you have a problem.
If you use sounds like unlock sounds etc, go turn them all off.. this was/pretty sure still is an issue in CM9 (causes audio_out1 to continuously wake up the phone from deep sleep and drains the battery like a mofo). Also getting rid of facebook (if it's installed) will help.. it loves waking the phone for no obvious reason.. even with every form of sync, background data, and mobile data in general turned off .
^^ you don't have to do that step but I'm pretty confident you'd have to anyway, so it's just easier to do it straight up. Then you can look for other problems.
Next, install "better battery stats". If you like to support developers, you can quickly buy it off the market. Otherwise it's free here if you search for the official thread.
Reboot your phone, then leave you phone for an hour or two, then check out whats happening in better battery stats. I'm not going to pretend I unerstand what half of the stuff it bangs on about is, but I digress. Select "since charged" and then check each different tabs of data (partial wakelocks, kernel wakelocks etc). You are really just looking for anything that stands out as a red bar basically. small amounts aren't a real worry/bound to happen. If it's bigger than say 1cm long, it's probably an issue. Then it's up to you to find out what the app/process is doing the damage . So either google or the better battery stats thread will be your friend at that stage. It was obvious what is was for me cause it said facebook but you might have a different experience.
Hope that helps. But the only way that's going to make a real dent would be trying to use it less.. lol.
Oh and if possible, turning on airplane mode would save a bit of battery in use. And of course the obvious ones like turn of wifi, gps, bluetooth, data, auto sync, soft key backlight and anything else you can turn off
Just do it what i say .. Download the full version of app. called juice defender from play store..install it and then see the magic by yourself ..i have been using the same ..it almost double up the battery backup through its advance settings.

Hello everyone.
Recently I acquired a Cube U9GTV tablet. When it comes to value for money, it's quite okay. However, I think that something drains its battery.
This is my first tablet so obviously I have no idea what to expect, but I have a Samsung I9000 running 4.2.2 and compared to it, tablet's battery is out of the league. My phone can stay up to 3 days being idle, taking no more than 1% per hour (of course without wifi/3g/gps, just cell signal). When it comes to my tablet, it can hardly last a day without charging, eating 2-4% of battery per hour. No wifi, no synchronization, no location access.
Maybe I just expect too much, but I some other users of this device report that their device can stay alive up to 3 days, while being completely idle. Mine cannot make it to a day.
Things I have done so far:
Clean ROM install, no Google account, no Synchronization, no Wifi, no BT
Deleted Phone.apk, TelephonyProvider.apk, MMS.apk -> the Mobile network signal bar in Battery status changed from red to yellow, battery drain decreased a bit
Disabled Media Scanning by Rescan Media Root
Stopped Google services running in the background (but didn't touch the cached ones)
My tablet enters Deep Sleep with no issues. But I noticed that the battery drop rate is not a constant, it varies and it seems that sometimes it drains the 1% per hour, but then something happens and hops to 4%/h.
The thing that concerns me is the Mobile network signal, which is completely useless cause my tablet is only a Wifi version, and I do not use external 3G modems.
I am unable to see battery usage in Settings, it just says it's unavailable. So I got myself Better Battery Stats, made a test and screenshotted results (see Attachments).
Why does it show No or Unknown Signal and No data connection at 100%?
If you have any suggestions or tips, share them with me please.
Thank you in advance.
Bumpety bump.
Don't punish me for spam!
I think we've ALL been here. Is there any uniform answer to this?
Let's be honest, I'm one of the not so frequent xda user, I always read several articles but have been, so far clueless.
I have the international model running on CM10 and constantly switch between ROMs of stock and CM, I've always liked AOSP ROMs, love the simple and uncluttered interface as opposed to the ever so bloated touchwiz. What else can I say? It has 32GB SD card and 16GB onboard storage, and it has a little trouble with 3rd party chargers (lose connection / disconnects every so often ) Its an old phone in technology time, but its still great.
So, I've tested wirh CM, stock and 2 other kernels which still make me feel like the phone is gobbling up a power plant everyday. One main culprit is Cell Standby which is very odd since it's usually just in my room (I use an other phone otg) and has a pretty decent signal (3-4bars)
On the most recent checks:
Cell Standby - 25%
Android OS- 18%
Screen - 15%
Google Services - 10%
Phone idle - 10%
Android System - 6%
And the rest are some of my apps..
I just recently started using Deep Sleep Battery Saver and wakelock detector. I'll send the info when the results are in for a day.
I'm not that fond of using 3G since data rates in my country are time-based and the KB-based pricing is off the charts. So I only use my phone for call and text and the occasional casual gaming and browsing (usually the cnet app)
I can only say that, if we could help on this either way, there are a ton of xda threads related to fast battery drain with varying issues because of Androids openness, I can only think if there would be some sort of centralized thread for this, or if you guys could help. That would be pretty awesome.
Ask any question or request anything so I could get this phone going. Thanks
Cell standby will be highest because you don't use your phone.
It's not a culprit,it is normal that it is up on the chart
But if you are experiencing any battery drain of more than 1-1.5% on standby then you have to look for an app or similar service running in background otherwise there is no problem
Press thanx if i helped you in anyway...
I don't think so. I left my phone's battery last night at 29% and after waking up 6-7 hours later, I got 16% left.
So that's around 13% consumed in one night without using it, or 2-3% drain per hour.
I already greenified Facebook and Lookout which were the biggest wakelocks, deep sleep gave me no noticeable difference even on Slumberer mode. I'm suspecting this is due to cell standby. the location which my phone was in had 3/4 bars of signal, wifi and location services are also turned off.
What's the big problem here really? I suspected it may be due to facebook but nothing has changed so far
Update: Signal strength is 73-80+ dBm, When I got home today the phone was dead from 16% this morning. The highest consumer is Cell Standby at 26%, Facebook is already turned off and everything, Still no perf difference.
So I also have a friend on and he's got a GS4, battery life was terrible for him since the kitkat update.
Anyone??

I have read the other battery problem posts and haven't seen that anyone has reported similar problem to mine...
Typically I have a full day of use with my Gear S (BT on; wifi, mobile and gps off) and come home with about 45-60% battery.
However, about once a week I have had it suddenly chime with the low battery alert after only 2-3 hours, same settings!
What is going on? Notifications from Google Now are kind-of excessive (once an hour), but don't have any special apps installed except Watch Styler and Zooper wearable widgets. Anyone else with random poor battery performance?

Mine has better battery life on some days than others. I haven't had it that long but all of my settings remain the same, but its definitely not as drastic of a difference.
Hmmm, wish it was that way for me. I'm sure one of apps is hanging in the background after being triggered or opened, though not sure which one or what else it could be. :-/
Same Problem
When I am work, my battery dies in less than 8 hours even with VERY little use. When I am away from work (weekends, etc.), my battery will go all day with phone calls and texts and even GPS usage. I'm wondering if it's related to the Wi-Fi or cell signal I get in my office. I have Wi-Fi turned off on the watch but it made no difference. Something must be "active" to cause it to drain that fast! Less than 8 hours with very minimal use.....WTF??????

Is your mobile network on the watch set to auto or always On? Maybe you can try turning it off and see if it helps save battery life..
I agree with the post about turning your cellular data off as the watch will constantly try to get information and if it is a weak signal it causes battery drain.
Well ever since i switched the cellular data to edge my battery consumption it reduced to almost blue tooth levels...about 3-4 % per hour [emoji2] i can can have it remotely connected all day with out any problems.

I've notice that some clock styles are huge battery drainers and mobile data on, eats up your battery like crazy, also motion. BATTERY IS THE ONLY BIG DISAPPOINTMENT THIS WATCH HAS
For me the trick was to never turn my watch off! I now put it in airplane mode overnight and deselect in the morning. I'm still not sure what causes my problem, but powering up the watch would result in about 20% battery loss per hour. I think it is a software loop running in the background after the watch engages in system update check. Now I get through the day with about 50% battery remaining and can use motions and even always-on.
