How long can you go with your screen-on after a full charge?

Hey guys... I just wanna know how long does it take your sensation to drain your battery while your screen-on... I have my brightness set to 50% and after 2 hours of screen-on, the battery is dead... I mean full charge to shutdown... Please share your experience and some advise to improve this... Thanks in advance...

Depends on other factors too but my screen on time usually falls somewhere between 3-4 hrs. However, like I said that is not the only thing effecting your battery life.

Well, watching a 40 minute TV show on mine uses 20% of battery with screen set to 100% brightness, so 2 hours should leave about 40% of battery.
This would suggest there's either something else using your battery, or there's something wrong with your phone/battery

5 hours if I'm really conservative with the brightness.

Sigh... i guess there is really something wrong with mine.. and i can't really find what is eating my battery... When it's idle with 3g on, it does not consume anything at all, may be just 3% for 3 hours.. but when i start to turn on the screen, battery life begins to drain so fast...and that is only at 50% brightness... This is just frustrating.. anyways, thanks for sharing guys... Much appreciated

It really depends on how u use ur phone, like me for ex. I use it as a music player also, so say when I'm driving I'm playing music bt screen is not on so by the time actual screen time is on, batt will have drained some thus giving me less display time per charge. (or playing a game). There's been a time I got a lil over 4 hours bt dint play music/games tho. And my fone is always on auto brightness

i have it since one week then i play too much with it ... 2 or 3 hours
i tried too much rom and to much kernel

Can anyone confirm that setting the brightness to auto will save more power?.. i read something in the other thread that it will consume more power because it will always try to sense which is the suitable brightness for the current environment you are into... Correct me if i'm wrong please...

Depends how I use my phone, and also how good the signal is. I would say 4 - 5 hours on average. I got 5 hrs 10 mins the one day last week
Screen brightness set around 30%.

That's nice... I envy you having able to squeeze 5 hours of your screen-on time..

Always set to auto brightness, feels like no matter what I do with the phone whether it's heavy gaming or light usage, the screen-on time gets to about 3 hours before the battery goes.

Just one question for all of you guys having more than 4 hours of screen-on time.. are you all rooted and have flashed other ROMs?...

Low brightness, but that's still pretty amazing.

Battery drains more on standby??

My sensation actually drains battery less whe its using somehing or on. This happen on pyramid3d. And miui frm tripndroid. Illike I'll listen to mussic for 1 hour, and it will be 100 to 96. And when I let it standby, it will go to like 88 in a hour. Is this normal?

I had an issue similar to this. Every other day the battery would drain in half a day (when usually it would last a good 12 hours +)
Under the battery usage tab it was showing the phone as being awake for almost all of the time (Even though I hadn't used or touched the phone)
I think it was a Kernel issue (Correct me please if I'm wrong, just a small time n00b) As I was using the stock shipped rom but just rooted.
Anyway, upgraded now, and it seems to be ok so far! *touch wood*
Would suggest you look under the battery usage graph and see what that tells you.

Ill reply in 12 hours. Since I just ubplugged from charger

You could've installed a bad app. Faulty/bad apps will stop the phone from sleeping. Look for apps that (when you install them) list that they can prevent the phone from sleeping in the permissions list.
If you've not installed too many, remove one at a time, leave for a while, and then check battery section in Settings to see if it's no longer staying awake.
If you find the app, contact the developer through the market so they can fix it.

Also, if you have it, keep WiFi connected when in range. Uses less battery than mobile data. Switch it off when you're not connected of course.

Quite possibly a bad battery. Your battery shouldn't drain when the phone is off.

Does it drain when the battery is removed from the phone?
Sent from my LG-P999 using XDA App

you should download a cm7 nightly my battery lasted from 10pm - 9am with 30% than i put it to charge

You can either do a factory reset or NVFlash CWM and flash a ROM to see if that fixes things. If not, then defective battery.

What these guys are saying is most likely, especially with that kind of drain. But also make sure you don't have any crummy apps, it apps that run when your phones off. Ex. Some weather apps run in the background and draindrain

You guys. He said that his phone was OFF while the battery lost its juice. It has NOTHING to do with what ROM, KERNEL etc etc he is using. Now for the op; simply just get a new battery and check if the problem persists.

Haha, yea. Read to fast, selective reader I guess. Thought I saw 'screen off' =)

Try the same test with the battery completely removed.
If it doesn't drain that fast - Then the phone is not shutting down properly, and most likely is the result of a nasty app.
If it does still drain that fast - Then the battery is probably faulty.

In your original post when you said you turn the phone off at night, you do mean actually turning it off right? Like shutting it down and not just turning the screen off, right? Just making sure we're all on the same page. If the phone is powered down then it can't be an app because apps can only run when you're booted into Android.

I would try to eliminate apps one by one. Freezing them with titanium backup or using better battery stats to see which apps have a lot of wakelocks. I had the same issue before.

Then its the battery. I had the problem with my g1. I would load the maps and use gps. It would say my battery is around 70% then after like 5mins the phone would get hot and then it would say i was at 30% or lower. Swap out for a new battery and it didnt do that anymore.
My g2x is kinda doing the same thing. But its a little slower. I turn the phone on in the morning 100% battery. Then use it for about an hr. (95-80%battery) put it in my pocket. Then about 2hrs later it at 40-35%. And the phone feels warm.
Also check your battery to see if it had a lump on it. If so then its a bad battery and needs to be replaced asap.
I ordered a replacement on ebay should be here by next weekend. Only $4

I don't think its the battery in this case.
Sent from my Flashback HC-TAB using XDA Forum App

I had a problem like this and still do at times. Part of it was the stock kernel I was running and the other part was the fact that the phone was not fully going into the low power state it was supposed to. I now only loose about 5 to 7% in the worst cases. That is better than the 20 to 30% I was loosing before.

[Q]Battery drain due to HW problem?

I serched the forum but didn't find an answer to this problem...
I'm having a serious battery drain issue with my sensation. I have latest italian BB by OTA update 3.31.401.5
Last night i had the phone with like 80% battery left. Today, 8 hrs later, i go wake up the phone and doesn't wake, and doesn't even boots up. I connect the charger and i have to wait a couple of minutes before it responds to power button.
First thing i do is go and see battery consumption stats, and it displays like 2h57m of use, and 88% of power drained by screen. Now, i know for sure the screen didn't light up for at least 1h before i could get to sleep, and i had used it before to install some apps, play a little cut the rope and fruit ninja and stuff, it had been disconnected for at least 2hrs before i got to bed.
I think it's pretty odd, and i guess it could be an HW problem.
The phone is unrooted and all stock

not likely, i bought a second original battery and shows the same problem
yesterday 30 mins of call drained 20% battery, light use drained the battery in 8 hrs, use i did was 30 mins of call, 20 mins of gaming (a little alchemy and 7 lvls of angry birds space), 6 messages, 1 email. Rest of the time screen off. wifi on for like 10 mins tops, mobile data always off.
Optimus 2x with this kind of usage did 2 days (40 hrs), this one 8 hrs? i refuse to believe it

Check for apps/services/processes running in the background.
This sort of battery drain is not normal so suggests you have an app that is using a lot of power

well i actually have not much of apps installed, and the only ones running in BG are media, google services, whatsapp, maps, touch imput.
Is it normal that with nearly no apps opened i have 309 MB of ram used?
Btw shouldn't be an app problem because i did an hard reset and the problem was still there

other info: the phone tends to get pretty warm. Not boiling hot but when it gets warm i.e. like after a phone call or a web browsing, it stays warm for like even half an hour later

back up your apps and data, reflash rom after complete wipe of all partitions, restore apps one by one and test battery life.

Haha nope not quite we mean like tap the "screen" entry so we can see how many hours of screen-on time you've had, and also possibly tap the usage graph then it shows when your phone was awake, when WiFi was on/off, when it was charging etc.

As much as I do like the phone. I'm quite annoyed at the battery life and am thinking of ways to improve it and etc. but it doesn't seem to be working. I get like 8 hours and by then it's at 30% MAX. Usually around like 20 or so. 10 hours and it's pretty much dead. Am I doing something wrong? my screen is only on for about an hour and a half or so, maybe 2 hours. Lowest brightness setting, 4g off, 2g on, wifi on.. that's about it. I mean as much as I love HTC, I can't love this battery life...

Yes you're doing something wrong or have a faulty unit. Make sure you flash a good ROM (I'm using aokp) and that's it. I have my screen at about 25% brightness and here are my stats which is quite acceptable.

Might be the 1% battery mod which has been added to the viper Rom (Don't know really)
I was too surprised when it was 1%

I don't have the screen time pic but it was just over 4 hours. Still had 1/5 of the battery left too! With this phone I just leave gps, wifi, antenna and sync on. It's so rare for me to NOT last a full day that I see no point in being conservative about use anymore.
