my battery doesnt stand one day with me.. when i charge it and it is 90% i shut down the phone open it again and it is 99%..what is this is there a problem with it .should i change it ??
another thing sometimes my phone has no network and after one day the network come back .what the problem ..is it a radio problem?
Usually battery drain is due to visual. u can check what was hogging your battery and tell us what u see.
After flashing to cm7 i also notice that my battery stopped charging at 90% but then it charged to 100% the next time.
About your network, does it happen often with your phone? Try some test with the same network on different phone before changing it.
At times i too have no signal, my family uses the same network and it happened to all of us, so we conclude that it has got to do with our telco.

1. Battery-life depends on numerous factors. With experience, major ones include
i) ROM in question
ii) Telecom signal strength
iii) Wifi or 3G usage
iv) Screen-on time
v) Some rogue apps
vi) Music all-day?
vii) Do you "game" all the time?
viii) Are you aware Android as an OS isn't that nice on battery juice?
A battery change should appear somewhere at the end of an exhaustive investigative list.
From your no network saga, I'd readily assume it's the poor signal strength that's mostly killing your battery.

If you are in poor signal area or worse right on the edge of a 3g reception, then the phone must work constantly attempting to hold on to a signal which in turn causes considerably battery outage, or off on the edge of 3g, must constantly change radios

If your connected to wifi and using it, are you gonna get better battery life VS being connected to either 3g or 4g/hspa+?
and Why if so?
Shoot im sorry, this shouldnt be in this forum. I thought I was in the general questions forums. MY bad people. Please move mods.

This is the General forum. To answer your question, Yes it would use less battery on WiFi. On a data connection the signal is not a constant and the phone is always looking for a stronger signal.
Thanks, thats what I thought. And ive noticed that connected to wifi my battery lasts a lot longer.

yes. And 4g eats your battery.
When I am only using the phone for data, I use WiFi when available. I turn on airplane mode then activate WiFi.
I don't know about that... when I'm on wifi my battery drains like a mofo. Weapon 3.0 ICS theme faux 1.3 kernel.
On every ROM and Kernel I've tried, Wi-Fi uses much, much less battery than 4G. I haven't tried any of the toggles / battery saving apps though so I'm not sure what effect those might have.

Do you disable data when you use wifi?

He shouldn't have to. If he's draining faster on WiFi then something is screwy with his setup.
On stock, cyanogenmod 7.1, and cyanogenmod 7.1 with various other kernels I've experienced increased battery drain with wi-fi on and connected with the phone sitting at home the entire day. Turn off wi-fi and let it just use the data connection to T-Mobile and I get drastically increased battery times. I'm assuming those of you who get better battery with wi-fi on are in extremely bad signal areas. Also, if you're on cyanogenmod have you turned off the auto wi-fi disconnect when sleeping feature? If you haven't then your battery life when sleeping should be the same as that of wi-fi turned off.
Wi-fi should always be priority if your in range.
Well my personal experience has been that wi-fi eats up battery like crazy. Same thing happens to the other smartphone users I know around here so I was surprised to see that people get better battery times with wi-fi on. Are you guys completely turning off your cellular radio? I don't like the quality and slight delay of wi-fi calling so my cellular radio stays on when I have wi-fi on.
I don't usually notice much difference between wifi and 3g battery drain here (no 4G for tmo here).
As someone already posted, my drain is worst when 3g signal is poor, like when I'm at work and the metal building interferes with everything.
Have you tried checking logs while connected to wifi to see if maybe some app or service goes crazy?
Nothing fishy going on when wi-fi is on. I get about 10-14 hours on battery with wi-fi on and next to no use of the phone vs somewhere around 20+ hours with wi-fi off and similar extremely light use. I keep meaning to do some more standardized testing where I literally don't touch the phone but life gets in the way and I have to make/answer a call or txt or whatever so I can't nail down any hard numbers. Typical experience on a slow day for me is that if I forget my wi-fi is on, my battery will be somewhere in the 3-5% range when I'm getting ready for bed while if I hadn't left it on, I can go to sleep and wake up and it'll still be hanging in there.

That's true, I've always believed that Wifi eats battery faster because someone(don't remember who) always told me that Wifi uses more battery because it processes data faster, but I always noticed that when I used 4g, it drains a lot faster.
I always blamed it on the ROM, but I can see that it's not the ROM's fault.
I have a huge battery drain, and i think that is because i have low signal (look at the picture).
I tried to recalibrate battery for two times, and use it for 2-3 days, but it's alway the same.
I get maybe 7h with normal use. 50% of the time with 3G/EDGE, 50% with WIFI. screen time 1h, and turned off Auto sync.
Can someone help me? I need my phone whole day, not 7h. :S
EDIT: I'm using stock 4.0.4 with matr1x kernel
Bump?
Can't really help you as cell reception is based on the quality of the carrier. I normally experience -95 dBm and I believe it is a cause for such high drain too.
The only thing I could recommend is try flashing a different radio and see if you get a better signal?
Sent from my Nexus S using XDA
BetterBatteryStats can let you know if it's not the radio. To test if it is the radio, try switching to 2G only.
Well, it was 3G-s fault. I switched to 2G and now there is no battery drain.
BUT, i still don't know why is there no 3G network in my house.
I have SGSII on my shelf, with the same carrier and it has 3G.
There is 3G at your house. It is just weak, much like me. A few too many concrete walls where i'm at.
Cell signals are done through waves which have to penetrate through walls and other solid objects, this vastly weakens the signal. Once you hit the ~-100dB mark your phone will start throwing more power into it's antenna to compensate, much further and it ditches 3G and goes to 2G assuming it has better coverage. Around the 100dB mark it tends to stay with 3G if data is on though which can start chewing through battery. It would be able to play around with the parameters but i don't see this happening anytime soon.
Compare the dB reading on your SGS2 and Nexus S. If it's much worse on the Nexus S, try flashing a different radio.
I have the same problem, i just switch back to 2g when i get back home and at night. for some reason, 2g networks tend to always have stronger reception
Anyone else noticed this? In areas of med to low LTE signal (-109 dBm), there are times when something locks up inside the radio and Signal Strength under Status will never change again no matter where I move the phone. During this funky mode, the battery is dropping rapidly during idle... Maybe 10% per hour. Something is wrong. During this same time android battery history shows yellow medium signal and voice calls work fine. There is also no runaway process cpu ussage or awake time. The only thing wrong and drawing too much juice is radio. If I toggle airplane mode or toggle wifi off/on the problem is solved for a while. I have VRALF2 firmware.

I have the same problem. Have went through many sim cards and factory resets. After 5 phone I finally have one that holds the signal a little better and does not go into this "funky mode". With the previous 4 (white 32gig) verizon phone I would burn through a battery in 6 hours at work. It would start with a drop in signal strengh at around -93 or so. Nothing would fix it. I finally got a blue 32gig and it seems to hold the signal to around -99. I don't know if I got a better batch of phones. But it seems to help me get through a day at work.

That's not normal. Where I work I get 3g primarily but also 4g in the front of the building.....in the far back I get 1x. I have had my phone totally drop data for a while (like the radio sleeps or something) but never had the radio stick between 4g and 3g. I also live right on the edge of a 4g/3g line and my dbm right now is 111 on 4g LTE......If this was normal I would have had the situation your having since my signal is basically identical to yours. I would return it or at the very least contact Samsung. I'm sure Samsung will tell you to send it in for repair.
I have very weak signal at my house also. S3 switches from LTE to 3G and 1X and sometimes loosing signal completely downstairs but upstairs usually I get solid LTE with around -99dBm and ~10Mbps transfers. During this network jumping my battery drains very fast also but I never had my radio constantly locked at one frequency or signal strength. And I can directly compare signal reception to my wife's Fascinate and S3 loses this competition badly. Fascinate never completely lost signal at our house and it rarely jumps to 1X.
I did a factory reset yesterday and so far so good... I''ll update as time goes on.
As far as signal strength goes in general,my wife's Droid Charge always pulls in a few more LTE dBm's than my GS3. Based on general public feedback, GS3 is below average on signal and radio issues. It's too bad because the rest of the phone is above average.
It's been 2 days after the factory reset and no problems with battery drain or radio lock up.
The only app that I could maybe try and blame is Elixir 2's create widget feature for signal strength. This always returned bogus values and may have embedded itself at an unholy level. Simply uninstalling elixir 2 didn't fix it.
If anyone still cares... I found my radio lockup and battery drain issues returned only after I reinstalled Better Battery Stats. I again removed it and will see if I stay good.
I've had this thought for a while, but haven't found any practical way of implementing it, perhaps having it out to the broader public may help.
LTE or 4G, as we all know, is fast and great, but it also demands more on our batter than good old 3G.
These are some of the scenarios in which I would love an app, or OS be able to make smarter decisions about the network.
1. When connected to WiFi - When connected to WiFi, our battery life improves when compared to 3G or 4G, but I find sometimes that even though I'm connected to WiFi, my cell network is still connected to 4G (at home, my 3G signal is full bars, but 4G is 3/5), thus, wasting a bit of battery.
2. When phone is in low data use state, or lengthy sleep - Often, when I'm in the office for example, my phone sits there in standby for hours at a time (my emails come onto PC, plus I wear a moto360 so i check notifications there). In these modes, LTE is of little use for me, yet it can often spend hours in LTE standby.
I've looked into IFTTT, and messed with other software apps, but I always end up with the same conclusion, that is, this would have to be manually done...
does anyone know a way?
If you have a root you can do with with xposed and gavitybox (smart radio). I think some other modules can do it as well.

Let me guess, not on Telstra. Battery life on mine with Telstra is superb, even with 1-2 bar signal. I guess that would be because it is a stable 1-2 bar, unlike the issues I had previously with Optus, were my phone would drop signal very often in built up areas

Yes, not on Telstra, but that is besides the point here. This is not an AU specific thing. I travel internationally a lot for work, and this would be the same when I'm overseas. In fact, not complaining about battery life at all, just think that the way the phone manages its connections could be improved - this is not a problem on the Sony, but on most phones.

Good tip. Not rooted, not intending to.
My S8 plus had terrible battery life compared to the reviews . I get an average of 3-5 hours of SOT
i opened the stock android battery monitor and couldn't see what was eating up My battery so i downloaded the gsam monitor and found out that the phone radio was totaling a 60-70% of my consumption even exceeding my screen power consumption.
But i had excellent coverage(always full bars and -70 to -60 dbms)why would my phone radio consumption be that high ??
And my phone could last up to 11 hours of screen on time with continuous wifi websurfing with no mobile data usage so i know it isnt defective
Well i decided to do some research and testing.
In my country the cellphone network companies signed a national roaming agreement in an attempt to allow better coverage , which basically means that i can connect to any tower in my country even if its not the one that belongs to my provider. Which makes my phone always looking for the tower that has a stronger signal and switching to it.
I then decided to put that theory to the test and downloaded an app that lets me see the towers i am connected to
Check out the madness

3 towers in an area of less than 300 meters raduis and my phone keeps switching up between them .
So no matter what i do i will get the battery life of a roaming device ?

That the same issue i am facing here. I'm using lycamobile during my visit in germany and i noticed a heavy battery drain during the standby. Usually i disconnect my phone from the charger before i sleep so i always loose arround 6 to 7% also i can confirm that roaming is actually consumes lots of juice specially mobile data. While in wifi network the battery life is great.
Try to use a local sim card like Vodafone or etesalat and compare it to the one you are using. Cheers

Aha i got your point now. Well i am not sure how you are going to solve this problem as you can't do nothing about it. Have you experienced the same issues with your previous android phones!
You shouldn't have any problems with battery as your network provider assigns automatically to the nearest tower to insure the best network reception.

The constant connection and disconnection from towers does drain battery
My previous smartphones always had a battery life that is sub par with reviews
So today i activated tge 4g service on my sim card as the national roaming doesnt work on 4g . And to have 4g u have to be connected to your providers tower only ... and guess what ?
