[Q] several turn-offs and turn-ons per day - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

Hi friends,
I have a question that deals with battery usage. I have noticed that when I turn off the tab (not rooted, TouchWiz and the new firmware updates installed), it uses either no battery or almost no battery. So the question is this: is it a good idea to completely turn off the tab when you do not use it, and turn it on again whenever you need to use it?
In my case, this may happen 3-4 times per day. I am kind of concerned that this act of several turn offs - turn ons per day could harm the tablet in ways unknown to me.
Also the second question is this: does it worth it to forget about the standby option and just turn off and turn on the tablet several times per day? I mean is this going to extend the battery life?
Thank you for your answers.

Moving to Q&A

Just use the freaking tablet to the bone, you will get a new tablet before your battery has its life depleted.
I used my P7510 recently in vacation to watch movies, email, browse etc. and I did not had to charge it for 10 hours of heavy usage at once. You bought the tablet to use it, not to keep it closed.

IMO, only fully power it off when you're expecting to not use it for a few hours and it's going to be packed up and inaccessible for that time.
Otherwise - I agree, you'll likely be purchasing a new device before the battery gets fried from too many cycles.

Battery Drain - hardware or software?

First of all, hello to everyone. I have been reading through a lot of threads here in the last few weeks after getting my HD2, especially the ones about battery life.
I have never owned a smartphone, so I have no comparison but I'm barely getting through 1 day of use when fully charged! And I'm not even using it that much yet, Wifi is off, no data transfers, just some texting and calls. I have installed Bandswitch and Battlog, didn't really help though.
Got the phone brand new (T-Mobile US) and haven't done any major tweaking yet, it's still pretty much stock with a few programs that I installed so far.
Do you guys have a similar experience or is it completely different? I love the phone, but if I dont even get through one day of use (and I want to use the phone in the future, not just for surfing but for music streaming or web browsing), I would have to bring it back.
Any help appreciated!
It's just something you have to live with, buy a spare battery, or the extended battery, flash a lighter ROM, adjust screen brightness turn off push e-mails etc etc.
I can get 2 days battery from very light use. i.e. a few texts and calls a day, no Wi-Fi, bluetooth or internet browsing. That's just how smartphones are.
So how do you do it on a daily basis?
My battery is fully charged in the morning and lets assume I'm using the phone for what I bought it for - some music streaming, gps here and there if I need it, some web browsing, calls and texts etc.
I haven't even started using most of the features of the phone and my battery has died twice on my already while I was out at night.
How can that be normal or acceptable? I can't charge my battery every 6h...

Maybe you shouldn't have a smart phone? Battery technology is ****, it's a shame, but it's true. The only thing I can suggest is a spare battery, I carry one everywhere.
I generally watch an hour and a half of video a day on my phone, text, call, use the internet and I can still make a 9 hour day with 40%+ battery left, and just incase I am out and about in the evening before I have a chance to get the phone on charge I have the spare.
But with that said half hours charge from the mains will give you a good 30% topup I very seldom have to swap the batterys and I use a pretty juicy ROM.

Given his kind of use, 2 days should be normal. Right now I'm squeezing 3 days out of this battery, and that's only because I swap it out when it's at 10%, otherwise it could be a little longer... and a few calls here and there is not the only thing I did with it... it's still my work pda after all
Since it's pretty much stock, unless it gets better with time (the first recharging cycles are the worst) and even after a hard reset it won't get better, it probably is something wrong not software related.
Install battclock and check the standby battery drain, shouldn't be much higher than 4mA, up to 7mA could be normal, any higher than that, especially if significant, and you've got something wrong, and found the cause to the short battery life.
First off, buy a couple of cheap oem batteries from here...
Now, these eBay batteries have performed slightly better than the original battery...
Some of us smartphone users are so used to poor battery life we have power charging cradles at home work and car just to keep the charge up... And have spare batteries every in case of emergency...
I take my phone off the charger at 6am to go to work... My avg day is 6-10 calls, 20 reminders, an hour of UNO, an hour as a wifi router and I return home at 5pm with 50-60% battery life...
they are trying to make batteries smaller and thinner so they can make the phones thinner and smaller so battery life is compromised. But you do need to give it some time to settle in.
Back up batteries and cradles to charge them are cheap and an easy solution. So are extra chargers to keep at work, in the car, etc. Most people can charge their phone at least an hour during the day and that should give you all you need.
The only smartphone that I didn't carry an extra battery for was the moto q9c, because it came with an extended life battery. But on these phones, that probably isn't the best option.
So what did you guys do to improve the battery life of your HD2? Are there any specific programs (I heared about G-Profile) you are not supposed to use or did you guys just deinstall all the T-Mobile Apps?
If I can just get 1 day of actual use out of it I am OK with that. I just dont want to have die every second or third day if I use more often than normal...
Any suggestions or may tests I could do? I feel like I could stream music on Slacker for about 90 Minutes and the battery would be dead...
EDIT: Just did Battlog for about 15 Minutes, my phone uses between 15ma and 31ma when in standby. So where do I start, how do I find the culprit?
I love huge screen HTC devices and Im a power user, so my solutions for power issues are:
Callpod Fueltank Duo
http://palmtops.about.com/od/accessoriesperipherials/fr/Callpod-Fueltank-Duo-Review.htm
Mugen Extended-size High-capacity 2600mAh Battery for HTC HD2
http://www.mugenpowerbatteries.com/
There is a 15% discount right now, better hurry.
Extra chargers and thats it! Now I browse, calls, emails, music, videos, TV stream (Slingplayer) and maximize all of the other features of my HD2 t9193.
Software and the end-user are the cause behind battery drain. I've got 2.5days out of moderate use so I don't think it's the hardware at all.
Methods for testing battery consumption and proof it is typically software related
Hi,
At the risk of looking like I'm trying to hijack this thread, I started a discussion on this particular subject a while ago as feedback on my finding after reading almost all the threads I could find regarding battery use on the HD2. Lude219 is 100% correct, the issue is always software related (yea, I know there might be exceptions to the rule) and my phone was a prime example of that.
See the thread below that explains how to measure your battery consumption, has logs and screen shots from users you have high consumption and also people who have systems where battery life is more than 48 hours so that you can compare your results.

I'm also sure it's software related. My phone would use app. 2% overnight with all connections closed. This i tested over months. Then suddenly without me changing anything drastic software wise, it pulled 5% per 3-4 hours. So after going thru all the cleaning routines nothing helped exept a good "ram cleaning" . Somehow or other the phone starts processes over time wich consume alot of power. One would have to look into it with a process manager to find out what exactly it is. WinMo seems to be quite sofisticated looking at all the running processes. So my view is , keeping the system tidy might be the only way to save the extra power.This is where the huge diffrence to other platforms seems to be, it can take quite a while until you have configured your phone the way you need it. I am useing the stock rom 1.66 German
thanks you guys for participating and sharing your thoughts.
But now, here is a thinker:
Last night, I let my battery drain all the way to zero and then recharged it at night. The only other thing I did was installing BSBTweaks and Touch X Taskmanager. I also changed my Bandswitch Settings to turn off data when not used and put it at 60 sec (instead of 500 sec before).
And I couldnt believe what I was seeing, I took my phone off the charger this morning around 8.30am and now at 7pm I am still at 84%!!! I did not use the phone heavily but sent and received a few texts, made 1 call and played around with it for a little bit. Similiarly to what I did in the beginning after I got the phone, but then the battery had almost died at 7pm!
I am super happy and hope it stays like that but cannot explain why all the sudden it is that different...
Hi everyone,
This is a very usefull thread, for me it is, thanks to everybody that answered.
regrding the last post, a noobish quesition is
”Bandswitch Settings to turn off data when not used and put it at 60 sec (instead of 500 sec before): how do i do this?”
I remember stumbling upon this setting the day i got the phone and started viciously going through it.
Somehow it didnt store in my memory the path i went that day so i can try doing what the man sugested.
So if anyone can lay a hand, much obliged.
Regards
i lost 12 pct over night in 9 hours with my radio turned off last night and only gmail and texts were open...
with battlog how do i do the test so it stays in standby? it keeps turning the screen on and off when i run benchmark
You may want to flash a new radio. Try a new one each day and measure battery life. I use radio 2.12.50 and have had a good experience.
yeah but with my radio turned off the radio shouldnt affect it shoudl it?
i use blackberry to stream pandora radio thru aux for about 8 hours a day and it still has 2 bars left after that.
HD2 just sits there and kills the battery lol
what kind of phone is that when you have to disable all its functions every time you dont use it?
seriously this is called unfinished product or poor design, that is beeing sold to customers as a next best thing.
you guys can argue with me all you want. i heard many excuses from users advocating the companies. such as. if you dont like this than pay more for a better product. well HD2 is a better product, its a 500 dollar phone damn it.
but you dont realize that even the "better" products suffer from same underdevelopment syndrome.
companies spend millions on consumer research and consumers spend millions on **** they dont need every year. cows eat grass, consumers eat garbage made by big companies.
where are the better products? they dont exist because it became "normal" to have a faulty OS or for your phone buttons to fall off, or battery to explode.
companies worked long and hard to make consumers get used to the idea that garbage is just a part of life, and worked long and hard to minimize costs of production, and cut corners.
which corners?
the final QA testing that is not beeing done by a company, so they can release the phone 3 months earlier, the consumers pay for the phone and test it.
we work for the company and we pay for it instead of getting paid.
the phone breaks oh how sad ,
company takes note(dont use this cheap glue or the buttons fall off, get a lil more expensive glue next year)
so they use better glue and cut another corner and we buy another "new and improved phone" and this time screen goes dim oh dang not again...and it continues.
do you disconnect your car battery every night so it doesnt die? or when you buy a lexus do you drive with your AC off because it cant pull the car around when ac is on same time as the stereo?

extended battery....

Hi guys, a simple Q&A here I hope!
I've had my device now for several months and find the battery life is abysmal, whilst there could be several issues like ROM, background apps etc I can't for the life of me seem to get more than 9 hours out of it. All I use it for in the day is music whilst at work and that's with sense disabled and the radio turned off also. From this I've just ordered the extended battery, but here is the question to see if I've made a noob error or not;
When I got the device I didn't do the 24 hour charge cycle, was too impatient about wanting to play with it, so is that the root of all my problems? I was under the impression that these newish batteries would only take a few hours and your away?
Any help/ lulz about me forking out £40 is greatly appreciated as always!
Thanks!

The 24 hour cycle isn't needed. I didn't do it and get a good couple of days out of it with moderate use.
Playing music on it will drain the battery pretty quick, as speakers/headphones aren't the most efficient form of activity to use a battery with. Official audio playback is 12 hours max, and that'll be quite a low volume with standard headphones.
Sorry to say, but it might be best to hard reset, and then try installing each program/tweak one at a time, and testing the battery life in between.
The battery issues we seem to find on here are usually caused by a dodgy program / installation / process running in the background.
I was thinking that, looking at task manager I seem to have a constant 43%-53% variable on the program memory, that's on the latest energy rom after a few hard resets, not really got anything installed either as I've simply linked shortcuts from the sd card rather than reinstalling after every rom change/hard reset, backlight is always set to 30% yet in the time it's took me to type this I've already dropped 3%!
With the new Li-ion batterys I really don't think there is an optimal way to condition the cells before 'normal' use. Some people absolutely swear blind by it, but after owning 4-5 HTC devices I've always found the WM OS to be a bit of a dog where keeping charge is concerned, and after a few trys on various phones I don't bother with charge discharge cycles anymore.
And as for the extended battery, I would definitely suggest getting a cheapy from eBay, you can pick them up for a fiver and they just as good at the HTC stock ones. Save yourself a few quid and keep your phone streamline.
I'm thinking my best bet is to reset the lot, hard reset phone and wipe sd, could be something on there maybe? Might just do the trick if I run the phone 'stock' and install only must haves if I need them, if same problem occurs, defective battery maybe?
Worth a shot I guess before spending more money, cheers for the feedback guys.
just a quick update, thought I'd try a hard reset, clean sd card, used myphone to restore contacts, 3g connected, standby for the past 70 minutes bar quick look on BBC sport mobile, already dropped 17%!!!!!

[Q] Question for S2 owners re: battery

Hello everyone,
A while ago (right at the launch of the S2, total coincidence) I made the transition from a "regular" cell phone to a so-called smartphone.
I took a look at the S2 and liked what I saw, but read absolutely horrible things about the battery (i.e. not being able to get through a day with it). To me, that's not an option as that means I can't rely on it and thereby defeats the purpose of a mobile phone for me.
So I looked elsewhere and got me a Motorla Defy (installed Cyanogenmod 7.1 on it). I'm happy with this phone as the battery usage is okay to me; during the week it easily lasts a whole day to 36 hours with plenty of room to spare (not going to claim a consistent 48 hours, but it could get there every now and then). It gets these easy 36 hours with the following usage pattern:
- Internet connection is always on (it switches automaticly between wifi and mobile internet depening on availability)
- a few widgets (stock quotes) are always on and refresh about once every 5 minutes
- e-mails refresh about every 5 or 10 minutes, not sure, I'd have to check
- usually facebook app is on as well in the background so I get notices when somebody sends me a message
- regular texting during the day
- a few calls every now and then, usually only a few minutes a day
- reading the news online with the browser, not constantly but checking every now and then
- general browser usage while looking for adresses or random info etc
- little to no gaming
A few days ago somebody told me that the battery problems with the S2 had lessened due to new Android updates and such. As my brother needs a new phone I was thinking on giving him mine and getting an S2 myself, if battery quality is any good.
So basicly, my questions:
1) can I expect the same battery durability of the S2 as from my Defy now that the problems are supposed to be fixed
2) can I also put Cyanogenmod on it (as I'm used to this and like it) without any battery problems
Any information or feedback in this regard is much appreciated, thank you.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
No thoughts on this?
Battery use is very hard to gauge because the phone doesn't do exactly the same every day. In essence, estimates on battery life are like MPG ratings for cars: different styles and circumstances dictate usage.
Having said that, the less the screen is on, the greater the battery life, in general. If you are not happy with battery life, there is an official 2Ah battery which should yield around 20-30% extra usage.
I don't think SGS2 had any real big battery problems, or at least my set has never had big issues. Pretty much the same battery capacity since I first got mine and now with the newer firmware versions.
At the end of the end it all depends on how heavy you use your phone, how strong WIFI/3G/2G signals you obtain, running apps/widgets etc. Sure, the battery life is not great on SGS2 but it's also no worse than other mobiles with similar screen sizes.
I'm sure you can manage 24h with your usage, if not then you can always later buy the higher capacity battery which Samsung have released. It's slightly thicker but barely noticeable.
i got my s2 about a month ago with 2.3.3, battery was pretty poor at the start, wouldn't last a full day, but with some tweaking, i can now get roughly 2 and a half days use, albeit with light use. currently looking at my juice defender status in notifications, and says phone has been unplugged for 57 hours.
what i did/use.
2.3.5 stock firmware
juice defender ultimate
froze wifi sharing, ap mobile, social hub with Titanium Backup
screen brightness down to about 20%
turn off wifi when not needed
Basicly, what I'm wondering about is whether, given the use above, I could unplug my phone at 6am on friday to go to work, and only have to plug it in again at 8am on saturday with room to spare for any unforseen circumstances
Seems I finally found the question to which no answer can be found on the internet

Terrible Battery on s3

I just bought my s3 a couple weeks ago and I have noticed that the battery life is pretty terrible. Last night before I went to bed I let it get up to a full charge while it was off. I had my wifi, gps, all apps, and 4g all off. I slept for about 6 hours and when I woke up my s3 was at 50%. That is pretty ridiculous for it to burn thought 50% while just sitting there. I have to charge my phone at least 2 or 3 times a day. Is this normal? I dont think it is, What should I do? Should I contact verizon and/or samsung for a new s3??
also, I only use my phone for pretty light internet browsing and light txting.
To me, it sounds like the processor is going full on all the time.
Try going into settings>battery. If media takes up most of the, take the sd card out and give it a full charge and see if the battery life gets any better. Report back then.
Btw. this thread belongs in Samsung Galaxy s3 section.
Could it be just a bad battery case? In your place, I would, as soon as possible, take it to where I bought it and try to change it for a new one. Warranty is to be used or not?
I am a new member, sorry I was not sure where to put it. For some reason it would not let me post a thread in the Galaxy S III section so I came here.
Also, I do not even have an sd card. I went to the battery settings and everything is pretty normal. I bought the phone at walmart, I really don't like dealing with them there but it looks like im going to check if they can replace it.
maybe try a different ROM? my friend says he got better battery life when he went to the cyanogen mod.
Best way to make the phone battery last longer is to stop it from automatically syncing with google, I limited my note to manual syncing and battery life improved dramatically
Well, most of the time battery depends on your usage and applications that are running.
If you already disables WiFi, GPS, 4g; and lowered the screen brightness, yet your battery is still going down too fast it might be the apps that are running.
Line for example eats off the battery of my phone. Without any other use, it takes away around 1 - 2 hours of charge. Even if you kill it from the task manager, it restarts a minute or 2 later as long as it´s installed. You might have either that or another app like that installed.
I usually have a whole day and something more with my battery. And I have a lot open. At least two messengers and push notifications, exchange emails always on wifi or 3G. If it is not any app draining your battery get it replaced!
its all about settings, mine wastes MAX 5 percent.. did you close the apps?

LG G2 Mini battery (?) Problem

Hi,
I bought a LG G2 Mini second hand that has been used for about 7 months...sometimes it takes 2-3 hours to get full charge and other times it takes 5-7 hours with the same charger and conection (the charger that came with the device and the wall conection), it doesnt even say that its on a slow charge
It happens sometimes also that the battery gets drained for no reason, leaving it iddle with only wifi and 2g it can las betwin 20 hours and 240 (the last one was only once, generaly what i feel happy to get is 120). When i see what is using the battery it says wifi, screen and a very little of system
Thanks
Sir,

Good luck
First of all Wi-Fi drains battery, this is a common knowledge. Secondly since it second hand also the charger can be" not-original. Those tend to mess up the battery good. Decreasing it's life.
I recommend using : https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats&hl=en
If it is software related this will make you understand what is causing the drain, may be a wake-lock..
If it is hardware related first identify if the charger is original. If it is not change it, if it is your battery is probably fulfilled its life for some reason. You may need to buy another original battery. If you want a long battery life you have to use original parts...
