[Q] i9020a AT&T/Best Buy Version Advice

Hello All,
Hoping to get some advice. I bought the official i9020a from best buy yesterday (on launch day) seems to be a great phone but I have a few questions and problems.
I unlocked the bootloader but did not root it yet
The biggest issue is battery life. Its terrible (like nexus one before applying the wifi setting trick after 2.3.4 terrible). this NS loses almost 10% of its battery power per hour on standby.
While on standby I have the following running
-wifi turned on
-3 push gmail accounts
Also I noticed that the hotspot doesn't work. when i turn it on it briefly shows 3G and the signal strength bars in green but then the 3G icon goes away and the signal bars turn white, my tablet and laptop can connect but no internet from connected devices and the phone browser itself - just page's not found
my baseband is: i9020aucke1
kernel version: 2.6.35.7-ge382d80
adroid-build 'at' apa28 #1
Build Number: GTJ61
Any advice on the above would be great, I can easily return it but would rather keep it.
Anyone else buy the official Best Buy version and having issues?
Also Anyone know if this phone is locked to AT&T? I don't have handy access to a t-mobile sim card.
Thanks in advance!

Flash new rom. I am sure ATT has some tethering lock on the build. That should be expected.

10% / hr is unbelievably bad (assuming the display isn't constantly on). What's consuming the battery in the battery stats?
Thus far no subsidized Nexus device has ever been sold sim locked (The Vodafone Nexus One, T-Mobile N1 and NS and the various Canadian Nexus devices). I'd be surprised if it were sim locked.

Thanks everyone for the tips. After my original post and now I finished the root and installed cm7.
Cm7 took care of the hotspot issue. Battery life is still pretty dismal in standby. Ill do a test tonight and leave it unplugged all night and post what used the battery the most in the morning.
Thanks again

no man, something is really wrong with your device. My phone loses ~1% in each 4hrs in stand-by (during the night).... I can easily stay 2 days with one single charge (with light use) and with everything ON!
edit: oh, and btw, you won't find better battery in any rom out there. stock rom with stock kernel is the best so far (regarding battery life)... i really tried every single combo and it's the main reason i'm back to stock after so many time (with several devices) using cyanogen. with cm7 i use to lose 1~2% per hour in stand-by!
edit2: you should make some complete battery cycles. Battery life in the first week is not really great, but not that bad anyway!

I think there is something pretty wrong with it
a little over 4 hours last night unplugged in standby/locked
start power: 75%
end power: 35%
most used
display 64%
android system 6%
cell standby 6%
Everything else was system stuff at 1%
Display seems to be the culprit in standby.
Hardware? If so I can easily exchange the phone
Thanks again for the advice

I bought the T-Mobile version back in April. I found that my battery life on day 10 was about TWICE what it was on days 1, 2, 3.... I guess the battery adjusted as it got used some.
I suggest you give it two weeks and then note your battery life again.

I have seen the "battery gets better over time" statements quite a bit on XDA and other forums. I'll give it a week or two and some cycles.
I have to say the "it gets better" is not something i have ever encountered on any smartphone or dumb phone i have ever had though?
Anyone also getting really really slow charging during the 1st week?

If you previously had a non samsung device it charges *slow* even on a 1A charger. No way around that.

thank you! yes - i should have probably mentioned that this is my 1st samsung smartphone.

Yes, it charges really slow and it wont be better. Takes about 3,5hrs to a complete charge.
Battery really gets better after 2 weeks, but even in day 1, never was so bad as you described.

Fixed!
Ended up returning to best buy swapping the phone. the new unit straight away showed normal discharge during stand by and normal battery when in use.
In the end a bad phone.
Thanks to all for the above responses!

ya you definitely had a bad dud...i was lucky in enough to get a good "dud". with approx. of 3 hours of display on, background syncing, and other moderately intensive tasks i was at a point where i was going on 1 day 12 hours 16 mins and still had 40% of battery left.

[Q] What to expect from RAZR HD battery life?

Hello all!
First of all, let me just say thanks to the whole xda forum community for making this such a great place to find answers and alternatives to Android users.
So, I bought myself a brand new RAZR HD (XT925) last week. It works just fine, its really fast, but the main reason why I bought it is failing me - battery time. I'm not a heavy user, just have a couple of apps installed like facebook and twitter, eventually I'll listen to some music on it, watch some youtube video. While I'm doing this simple tasks with the screen on, I'm losing 1% of battery every 7/10 minutes. And if I try and load a game just to see, 15 minutes of gameplay will take me as much as 6% of my battery. That is so NOT why I bought this device.
So I went on a journey to find why this was happening. I've tried updating to JB, no better results. Downgraded to 4.0.4 stock firmware, wiped to factory defaults, didn't install ANYTHING apart from what it actuall came with the stock firmware and battery calibration, which I did after changing roms, and the results were the same.
While I was sleeping, the battery seemed to stay a bit better. My GPS and bluetooth are always OFF, I only turn Wi-Fi and 3G on when I need to use it, otherwise its always OFF.
I`ve charged it to 100% 24 hours ago, and BARELY used it, and now its at 34%... is this normal?
Any ideas are welcomed, and if there are other RAZR HD`s users out there with the same problem, please post here! Thanks!

Its not normal especially with radios turned off, and more specifically with 3g turned off. I keep everything on except bluetooth and nfc and can expect a heavy day of screwing around with it, to get 16 to 20 hours with 6+ hours of screen on time. It looks like you really have barely used yours at all.
As for ideas, warranty if you have one? If not then a factory restore might help. Try it from the GUI and if that doesn't work then you can do one by getting into the menu at boot time by holding volume up while turning it on, volume down to select (you have very little time to find your selection, volume up to select , select recovery, then when you get the green droid laying on its back hold both volume buttons down at once and let them go. You might need to do it repeatedly to get it right; just middle click the volume rocker a bunch of times until you get a menu.
Pull everything you want to keep from your internal sd before doing a factory reset because it will be erased.
First things first though, check your wakelocks using better battery stats. Mine are high even when the phone is not in use and with Google Now turned off. Google apps (I think is the problem) still wake it up like crazy yet I get the stated 6+ hours of screen time on a day of heavy usage. Also, I noticed that setting wifi on and leaving it to a policy of never wake up when sleeping is better power savings than having wifi off. It shows up in my usage though as it causes the phone to wake up a lot if wifi is turned off manually opposed to letting the ROM handle it and in some cases it comes on in the background so damn much that its half of the day.
You aren't the first person with this sort of problem btw. There was another thread a while back but I didn't follow it to see if it was widespread.

I have Juice Defender Plus running on my XT925 and I regularly have 75%+ battery left at the end of the day with pretty light use. I leave my GPS on all the time. WiFi is on 100% of the time I'm at home. I leave 4G off 100% of the time as there is no 4G coverage in my area. I find the battery goes down a lot quicker when I enable 4G, even when I'm not in a coverage area.
Try turning 4G off and install JD. See if that helps.

I'm having terrible battery performance after upgrading it to Jelly Bean. I'm running Jelly Bean 4.1.2 update via OTA (98.50.20004.XT925.Vivo.en.BR). I have the screenshots and I can post it here after my phone charges. Battery lasted today for ~10h 44m with HSDPA+ on most of the time. Screen on for about 2 hours with brightness set to 30%. When using it, battery discharges really fast. A simple Temple Run Oz short gameplay takes 5% of the battery. Battery dies in a flick of an eye. I cannot believe it's normal.

With ICS 4.0.4 and green power app installed, my battery would last for almost 3 days with wifi on (at work and at home), HSDPA+ whenever wifi is off and light use for other things. After the upgrade, battery drains way faster and yesterday I had a really bad experience reported.
With same use, my battery lasted 19hr only!!
The solution that I have found so far was turning wifi and 3G off all the time and turn on only 2G. Internet will still work, sync emails, get whatsapp messages, know who is making viber calls. If I need to use better internet speed, like call viber for instance, I will turn my HSDPA+ on or my wifi on.
I know this is not the best solution, because you have to change HSDPA+ to 2G manually all the time (as far as I know, smart actions and the green power app still can't control 2G/3G/4G switch).
If anyone has found a better solution, let me know.

I wish my battery lasts 19h. With HSDPA+ on I have now 34% after 6h and 55m. What's your OS version?

The word is, for some reason, HSDPA+ is killing battery fast.
-Sent from Marino's Razr Maxx-

Today things got worse. Yesterday the overall performance of the phone was terrible after JB update, plus terrible battery performance so I did a factory reset via GUI. When I'm out I need HSDPA+ on because I receive messages thru Whatsapp and Viber mostly and I pay for a better data plan with a faster connection, so I need to use it. First 5% of my battery was drained in the first 40/50 minutes unplugged with a screen usage of about 12 minutes. The phone heated all day long with no usage. I think it's really weird. I don't know if there's an app causing it, or a sync. I have Facebook, Google, Last.fm, Twitter and Whatsapp synced but it was not an issue in ICS. I could let HSDPA+ on all the time with no heating and battery after 6 hours would still have 60%.

That doesn't sound normal at all. Under very light use, the phone should last for a couple days.

What applications are you installing?? This phone has the best battery life of any android phone I've owned.

My Razr HD with ReVolt 4.2.2 ROM and some mods has the best battery life I've ever seen in any Android device.
At this picture that i took last saturday (14/09/2013) i had 3:40H screen time and still got that 65% battery left.

[Q] Battery life getting worse - How to check for draining apps?

Hey guys,
A common question: My Nexus 5 seems to suffer from energy drainage, as I'm not getting the Screen on Time I'm used to. Ever since I got the phone, I've always got about 2:45 - 3:15 hours of Screen on time and in the past months, that hasn't changed, until the last few weeks, as I'm getting a max up to 2 hours of screen on time, often up to 1 and half hour..
Not much has changed. Same usage patterns, not really any new apps that I regularly use and screen brightness (50%), Wifi (24/7 on and won't turn off on sleep, 90% of the day on WiFi), 3G (normal use), GPS (off), bluetooth (off) I use on normal base.
Also the usage graph that shows how many % per app is used hasn't changed ever since. 25% screen, 15% android OS and all others a few percent.
So I'm unsure what app/thing is the boogyman, or how I can check what is; hopefully any of you can help me!
I wouldn't mind a factory reset, but I'd prefer trying to use on-device checks before I perform a factory reset.
Thanks!
P.s. I'm not rooted (yet, still unsure whether to or not. Kinda happy with the 3 hours I'm used to. Not interested in a different rom anyway), so no answers that require being rooted. Thanks!

If you're rooted you're going to want to use Better Battery Stats. I believe there's a version free to XDA members, somewhere. It'll give you extremely detailed information about which wakelocks are eating up your battery. There are a ton of threads on here (my favorite is in the Samsung Skyrocket forum) which explain the various wakelocks and how to minimize or get rid of them. If you're not rooted, I'm not sure what would be able to help.

Not rooted - Updated the OP. Thanks anyway!

Do you have anything running as a service in Settings> Apps> Running that wasn't before? It might be the latest Google Search or Play Services updates.
Could also be strength of signal or if you were traveling more than usual. Any number of things, not much we can do without BBS or Gsam stats which would require root for meaningful results. Otherwise you could screenshot your default battery stats including the graph, screen on time, and detailed stats for any apps using more than 5%.

Any links to the better battery stats thread? I'm having similar issues. Running the latests Beanstalk

You should check social apps setting for repeating sync; Facebook, twitter or skype..

Without root and gsam or better battery stats.....this thread will just be full of guesses I'm afraid.
Have to see your Wakelocks. Otherwise no one knows the issue. All guesses.

Battery Life Decreased After Updating to 5.1.1

Before anyone asks I have searched, Googled, looked on reddit, and gone through these guides on xda:
http://forum.xda-developers.com/galaxy-s6/general/guide-to-battery-life-t3092593
http://forum.xda-developers.com/galaxy-s6/general/guide-battery-performance-tips-t3072049

I have a Galaxy S6 fro Rogers in Canada (no root) and I recently updated from 5.0.2 to 5.1.1 and my battery life has gone to crap, my usage patterns and apps remain the same as before. Previously I would get about 4 hours SoT, 5 on a good day. Now I can barely get 2.5 hours SoT. I have no other problems with this phone, none of the RAM issues, lagging, or over heating other people have mentioned, my only problem is the poor battery life.
The apps are primarily use are Facebook, Puzzle and Dragons, Messenger, and Chrome, I realise that these are battery guzzlers but 2.5 hours is ridiculous and I used to get more using the same apps. I typically start using my phone around 8am from 100%, and by 5pm after 2.5 hours SoT it is around 20% battery life, previously it would hit 20% around 11pm with about 4 hours SoT. No apps are draining a particularly large amount according to GSAM.
To reiterate the things I have done to improve my battery life are:
1. disabling unused apps in application manager
2. setting brightness to lowest setting on auto
3. restarting phone
4. restarting phone in safemode
5. clearing cache
6. performing a factory reset after updating to 5.1.1
7. leaving wifi gps off when not in use (but I'm not constantly turning it on and off either)
8. Greenifying apps I use less than once a day (but anything with push notifications is not Greenified)
Additionally I have not moved or anything and reception in my area has always been decent. Any suggestions for what else I should do? My phone is still under warranty, should I send it to a service centre? Or should I try rooting it an actually deleting bloatware and having an ad blocker (though this would void the warranty...).
Please advise! I am very frustrated with this battery life.

Im having the same issue after updating the GS6 on Wind (Canada) to 5.1.1. Terrible battery life and Android OS draining battery as well. I barely get 2.5 SoT.

I'll join this unfortunate crew. I have to charge everyday before leaving work in order to get through the day.
Take off the charger at home when I leave and by the time I get to work(30-40 min drive) I'm at ~95%. By lunch I'm down to around 50%.
Hoping Android M fixes some issues

Clear cache in storage option and reboot! It will very slightly improve!

http://communityforums.rogers.com/t5/forums/forumtopicpage/board-id/Android/thread-id/31962/page/32 Read through the last 6 or 8 pages over there. A lot of unhappy people with Rogers right now using the S6. I'm in the same boat. Crappy cell service, times it will show bars of 4G but then tell me there is no network connection. Try to make a call with full bars at 4G and it will say not registered on network. Text messages being sent and received twice automatically. No connection at all in places my HTC used to have 4G if not LTE. I had to send my S6 away for camera repair for a week so I pulled back out my old HTC M8 for that time and my connection was stable and awesome everywhere just like I thought it should be. Now that I'm back on my S6 it's barely hanging onto EDGE in places I had full 4G bars on the HTC like at my desk at work. Places I spend a lot of time at.
I suggest you call Rogers and talk to the tech support. Tell them your issues. The more complaints the faster the issue will be resolved. It sounds wide spread so don't waste your time trying to fix it yourself.

Thanks for the link, I didn't think to check the Rogers forums, I'll call their tech support to let them know of my issues and hope they are working on something.

I also have this issue. I was able to make it through an 8hr work day before the update. Now it's down to 10% or to completely dead. My usage at work did not change. Sucks that I have to plug my phone into my car just to get enough juice to make the drive home.

Just to confirm are you guys all now on 5.1.1 and is battery life the only issue you are experiencing?
I talked to a rep with my carrier (Rogers) and he said that the known issues were to do with connectivity (calls, data), but not with battery. He said battery issues that could not be resolved by a reset should sent in for service.

There was some discussion in various places about cell standby being a HUGE drain on the battery when connected to WIFI.
My issues are data and call related. I've never been one to care that much about battery but it does seem off from what I'm used too and I'm seeing some long times on the mobile radio being active.
I think it's safe to say that all of this stems for the 5.1.1 update. Cell reception "problems" can lead to big battery drains and if our phones are having issues staying in tune with the towers, it could cause big battery drain.
Keep an eye on what might be causing your battery drain though. It might be something silly like an app trying to do something.

I have also noticed a sharp drop in battery life now that I'm on 5.1.1.
USA AT&T.
I'm really at a loss. GSAM says "Android System" under apps as well as "Phone Radio" are the highest drain.

Nexus 5 battery drain - new battery, new ROM, still persists

My beloved red Nexus 5 starts acting up... the battery drains extremely fast. Some weeks ago, I could barely make it to 2pm without having to recharge after unplugging. So I got a new battery (directly from LG, so definitely a genuine part) which improved the situation, but didn't completely solve the problem. Additionally, I flashed a CM 13 CAF ROM (using myfluxi's kernel) onto the N5 - I enjoy it so far, but there was actually no further change converning battery life.
Right now, the phone is at 10% after being unplugged in the morning at 9am. Wifi, bluetooth, GPS and mobile data were constantly on, cell signal was mostly perfect, wifi was connected for about 3h, bluetooth was always connected to my Moto 360. Screen on-time is about 2h and I listened to music using GPM for about 2h. The battery settings do not indicate any app using up too much battery power - it shows the display at 15%, cell standby at 10% and then several apps.
What do you think - a Nexus 5 with a new battery should make it through a day, shouldn't it?
I remember my first Nexus 5, back in the days with a G watch, making it through a day without any problem with 15-20% left when I plugged it in before going to bed... because of that, I start to think if there might be a bad electronics part, like the display backlight or something on the mainboard, using up too much power without being noticed by the OS. Is that possible?
Thank you very much for your advice!

Read and post in the battery life troubleshooting thread stickied to the top of this forum, it will help logically determine what is using your battery.
You have a lot running at once, so difficult at the moment to solve your issue. It's better to turn things on/off one by one to make logical conclusions whether it has any noticeable effect.
The best logical way to conclude if it is a hardware problem is to go fully sock no additional apps no root etc, see if it 'drains' by itself
If not hardware, then 99% of the time it is a bad app(s) keeping your phone awake

This is likely not the case, but have you checked the CPU settings? I've only encountered such a drain while using performance governor together with overclocking.

Same here
I have the same problem and I have been banging my head about it, I don't really use my phone for anything much else than a phone and I kept having at least 3 days of using it with no problems.
Now the phone barely lasts 2 days and even switches off in the middle of the night...

In the OP's case, his drain is likely caused by having GPS on all the time. That will absolutely devour battery life, so he could save himself some grief by turning it off until he than your phone turns off occasionally. First guess would be the power button going bad; that is generally the reason for needs it.
For you, who knows? You've not given any information, otherthat type of behavior

Yes, sorry about that I was a bit annoyed at the phone. I found and fixed the problem. Go to settings > apps > disable google fit > click yes when it gives you some notifications about how you'll lose data or stuff like that > and click force stop at the end for good measure.
I am in my second day now of battery life at 59% with a looooooooot of talking today , I mean more than usual so it is definitely a fix for me. Hope it helps
Take care gents

Again same problem
Hi all,
Unfortunately I have better battery life but I am again losing a lot of battery.
I have a screenshot but I am unable to upload it sorry about that.
I use my phone mainly for calls roughly about 15 mins per day at the most in total ( not a lot at all I know) and I also have my bluetooth on at all times cause I have LG G Watch.
thing is that I have never had problems with the battery before. When I say before back in the day I still had my LG G Watch ( I have it for about 6-7 months) . Problem with the battery started roughly around 1 month.
Location is off, wi-fi is on on very rare occasions throughout the day when I need to check my e-mail and mobile data is the same. Navigation is used only if needed.
The real problem is that before I knew what was draining my batter now I have 79% of battery usage and I have 5 apps listed that drained each 1%
Android System 1%
Phone Idle 1%
Screen 1%
Google play services 1%
Android OS 1%
Where are the other 15 % ??
It is weird I really took pride in that phone and his battery life, I know that it is mainly because I don't use it as a regular used do i.e. gaming, facebook etc, but I still want to charge less than 1 time per 2 days or less
Thanks in advance
Regards
Nik
