[DISCUSSION] Touchpad Battery Drain - TouchPad General

I find that my Touchpad seems to lose quite a bit of battery while it's sleeping overnight, when compared to something like my Nook Color running CM7 n173. The Touchpad will lose 4-6% sleeping over 10 hours, and the Nook will be hard pressed to lose 2.
Is there something wrong with my battery, or a setting I should be changing (wifi and backup are off)? Or is this normal for Touchpad deep sleep?

are you saying you have wifi and backup off or asking if you should turn them off?
mine probably looses that much in that period of time with everything on and idling...

Yeah, they're both off when I leave it overnight.

Well my touchpad has been off my touchstone since 7 this morning, now 15:00. I have checked twitter, facebook and ebay about 4-5 times since then and my battery is on 100% . Thats with 3 programs running and WiFi on.
I can't give you on overnight figure as it sits in my touchstone

Does it really matter if you lose 4 to 6% in 10h overnight? As long as it doesn't drain at a stupid rate with wifi etc turned off and whilst doing nothing, surely there's nothing to get concerned about. Frankly, I have no idea how much battery mine loses sleeping, or doing anything else for that matter - I just use it, when the battery needs feeding I plug it in - drama over

why wouldn't you just turn it off then... or was this just an experiment to see what kind of battery life you're getting

With backup off and wifi on, OCed to 1.7ghz, my battery stays at 100% if I leave it off charge all night, around 7-8 hours.
Some moderate use throughout the day, and watching some YouTube videos before bed, wifi on and brightness up, mine easily lasts 2 days before needing a charge.

did a test... with backup and wifi on with 3 email accounts being pushed... unplugged and fully charged at 3pm... 9am this morning i'm at 75%... that's with some light usage as well... not bad for 18 hours
i'm over clocked at 1.7 with warthog kernal and have all the suggested patches installed to speed up performance...

Quick question - what's the backup that everyone is talking about turning on/off?

Battery Drain

Hi,
I've been noticing that my Hero has been gulping battery down VERY fast.
In general, the battery lasts 7-8 hrs, which is not acceptable (I'm out for 12+ hrs).
My usage is not heavy. Wifi, Bluetooth and GPS are rarely, if ever, on.
I do read some news and surf the web a little but only for 2-3 of those 7-8 hrs.
Is my battery life normal?
I've been reading people achieving 12+ hours with their stock battery...
2 or 3 hours websurfing is very heavy on the battery, much more so than phone calls. One of the biggest drains is the screen and you having it on for 2 - 3 hours is going to drain the battery I guess
Seems very poor, much poorer than my iDevice that I use more frequently.
Today, after flashing the 2.1 ROM, it has gotten worse.
Battery's down to 40% in 6 hours, and Battery Usage shows 50% phone idle, 50% cell standby.
I've not even touched the phone since unplugging it 6 hours ago ;S
Is it possible I've a defective battery?
If your battery is down to 40% after 6 hours of it being idle (no screen but switched on) then either you have some power hungry app(s) running in the background or the battery is defective.
At the moment my battery is showing 40%. It was last charged about 40 hours ago, and I have had it switched on the whole time with some light use, picking up emails in the background and occassionally switching the screen on.
I ran task killer and sync was off.
One thing I didn't do was charge it for 10-13 hours straight on first charge; I just unplugged it when the led turned green in ~4 hours (impatient...).
Could this have affected battery life?
Nope - when the LED is green it is fully charged. No minimum charge times suggested in the manual.

That is amazing battery life, I never get more than 24 hours with similar use... what ROM and radio are you using Peter? Also, where are you and what network are you on?
I am in UK on Orange, and have standard Orange ROM and Radio - not the latest one but the one they had before 2.73.61.5.
I have read lots of complaints about battery life, but I think mine is fine for a smartphone. I am a relatively light user of a phone - don't do lots of surfing or watching videos. A few phone calls, very few texts, checking emails and listening to some music is all I normally do with it. The other thing I do use it for is I always have the sat nav on while I am driving, but in that case it is plugged into my Brodit mount and charging from the car.
This latest spell may have been helped because I have not been out over those 40 hours - spent the weekend at home, which means that the Hero has been logged into wifi rather than trying to use mobile data. And not used it to make calls or texts or used the music player.
I notice keep Internet connection active take a lot of battery. Go to settings and turn it off and try to see whether the problem exist. It'll will take you a few seconds to re-establish the connecting whenever you need it... not so unbearable considering it'll save a lot of battery.
Same, I notice the mobile chip is using abnormal amounts of battery.
In the morning I watched a 40 minute episode of drama.
Battery dove from 100% to 65%.
To preserve battery life, I turned Airplane mode on.
When I was done with the episode, there was still 55% battery left!
I'm pretty shocked at the battery drain.
I'm using one of the new 2.1 ROMs. They're known for having a bit of a battery-hunger. I solved it by installing the app Ultimatejuice from Market. it's a pay app, but it's worth it. It's also another app called juicedefender (free, less options) that I used before I bought the Ultimate. It also worked good! Now my battery lasts the whole day without any problem

[Q] Sleep mode battery discharge rate on different ROMs?

Let's collect some statistics regarding battery discharge rate when tablet suppose to be asleep, like overnight.
I'll start:
ROM - TnT lite 4.2, WiFi On, BT Off, in 10 hours 14% charge drop - 1.4% per hour.
with WiFi Off - around 1% per hour.
I was killing all apps on background before going asleep but this does not affect discharge rate too much, maybe 0.2% and as well might be just measuring error.
What is your tablet's discharge rate?
vegan 5.1.1 clean install, no additional kernel/OC tweaks
lost 30% over 6.5hr of sleep. battery usage shows very little idle time and alot of "android system". i wonder if that means something stayed awake and kept the tab from sleeping or what. o, and wifi was on and awake the whole time too
anyway to put this thing to sleep and last a few days like my HTC mytouch3g when i put it into airplane mode? that phone would drop to the lowest clock speed and sleep with very little battery drain

Why not just power it all the way off? Deep sleep is essentially Off anyway, minus the bootup time.
Cold start is about 50 seconds. When starting from standby - almost instant.
It would be nice if our GTablet can go into standby and don't lose charge with that rate.

Nice, but impossible. Just plug it in overnight. If you want it "always on" you can expect about 16 hours of standby with 4-6 hours of use mixed in. I'm so used to daily charging it doesn't even bother me anymore. Just really happy this thing goes all day on wifi without deep sleep... good enough.
Well, I am inclined to think that this is a software problem (Android OS). Xoom with HC does ok when in sleep mode. Someone say 3%-4% overnight.

Only way it would do that is deep sleep. As in, nearly off - everything powered down except ram, CPU halted.
That's essentially the same as putting your laptop to sleep, vs power down.
The GTab's deep sleep sucks. Not sure what's wrong with it, but it's below the level of android. So it could be a firmware issue. I'm happy with the 2-3% per hour drain when "on" but screen off, connected to wifi, able to generate alerts and alarms.
So, my interest was piqued
I use pershoot's UV/OC kernel, keep wifi on all the time, and use softlocker to make sure my gtab *never* deep sleeps. This is on Vegantab-ginger.
I installed batterymonitor widget, and am collecting data.
First interesting tidbit, my "screen off, but wifi on/not really asleep" power drain is 125mA
Given the 3650mAH rating of the battery, that gives me 29.2 hours total standby time in this state.
Working backwards, that's a drain of just under 3% per hour.
You're actually seeing MUCH WORSE than that, at 4.6% per hour (30% over 6.5 hours) so I agree with you, your software is doing something very bad. You can get nearly 50% better battery life by using gingerbread, pershoot's kernel, and keeping it from going into deep sleep
my tablet lose near 10 %

Any more details? Number of hours on standby? ROM version? Was it deep sleeping (wifi off, clock/time not updated until a few seconds after power on?)
Assuming 8 hours or so sleeping, this is much closer to the expected 1.125%/hour discharge rate for "deep" sleep, or about 90 hours total on deep sleep standby.

if that was indeed true (that you manage to get your tab to sleep for 8 hrs and only losing 10%) then i want whatever you got. I want my tab to be able to sleep for 3-4 days, even if it mean having to settle for JUST 1.0 Ghz
The lowest I've seen so far in batterymonitor widget is ~108ma draw (screen off, 214mhz clock, wifi off)... if the thing goes into "deep sleep" then batterymonitor (and everything else) stops dead, since the cpu is halted - you'd need to poke it inside to see what the load is when deep sleeping.
108mA gets you to 33 hours. To get to 72 hours you need to get the load down to about 50mA. That's the budget to keep the ram chips powered, and the on/off buttons
Battery drain with ext3 partition and S2E?
Is there a perfect way to check what's draining your battery? Recently I've been noticing that my battery consumes almost 20% of charge during night, whereas it used to only eat about 5% in my previous installation of CM7.
First install of CM 7.0.3 - Good battery life, night drain is only about 5-8%.
Second install of CM 7.0.3 - Worse battery life, night drain is about 25%.
The main difference in the second install in that I have made an ext3 partition in the sd card and I am using S2E and have moved some apps to the sd card. Will this consume more battery?
Had a look at the battery history in spare parts, and I see that the partial wake usage by Maps and K9 mail topped the list. Uninstalled both to see it they were the issue. I have Juice defender plus where I have configured data off hours from 12:30 am to 6 am. Still it drinks battery. Any thoughts?

[Q] Das BAMF 1.6.3 battery drain

I'm just curious if anyone else has experienced excessive battery drain from this ROM?
In about 2 hours I dropped a good 30% from a 100% charge with very little use. When looking at my battery usage statistics I of course saw the screen taking the most which is normal, but the second was Maps?
I did have my location services on, does the htcsense.com deal burn through battery life because it's updating the location constantly?
That's the only thing I could think of.
After turning off gps and htcsense sync I've lost maybe 7% over the course of 8 hours?
me too, my battery life is Horrible i was down 30 percent within an hour, I do have htc sense hub on maybe i will turn it off, otherwise i need to look for other options
12h 9m and I am at 17% Bamf Remix 1.6.3
I would say that is pretty good especially since about 3 hours I was in a horrible signal area bouncing form 1x-4G.
To answer your inquiry yes anything that needs to constantly update your location whether it is through Dedicated GPS, or triangulation will use more battery. Two known culprits for this device and battery life are HTCsense.com account, and even more IMO is Facebook for HTC sense. Sometimes it seems to get stuck while syncing Facebook contacts.
What I do is add my account let it sync everything and then turn off contacts sync. I ended up turning it off completely and just turning it on once in a while because I don't use any social widgets so I check Facebook through browser.
1.6.2 ran 4.4.6 kernel and I would say that it more efficient on battery then 1.6.3 which runs 4.4.7 kernel. Each device has it's own personality though.
not a big fan of 1.6.3. just doesnt seem to run smooth and sync right.
I think I was better off on 1.6.1 too.
Not sure what I have going on or if its related, but I put my phone on the charger overnight (8 hrs or so) and it's 100% when i wake up. Within 3 minutes of taking it off the charger it drops down to 94%. If I put it back on the charger, it will charge for about 10 minutes till 100% and then the same thing happens.
Running 1.6.3/4.4.7
Any thoughts?

This has been discussed a billion times yes. Check the common battery calibration threads.. this is very normal
I am running 1.6.3 coming from previous BAMF roms.
I had lots of reboot issues with the new radio (.7 CDMA and .6 LTE fixed that) but battery life is ok. I am only on 3G in my area.
Full day of normal use at work and i am still over 50% before bed.

Alright. Thanks!
Sent from my ADR6400L using XDA App
Had similar issues where battery would drop to 95% right after a full charge. Charged to 100%, did battery stat reset and then rebooted. Now battery is acting normal.

[Q] Truth about Battery Display after flashing custom ROMS

Hi XDA,
Ive been getting alotta help from you, great developers, and had this question
that dont think has been solved yet. (I searched for 2 days)
So my current situation is;
Im running the latest energy rom (sense 3.0) with stock kernel, (as it was recommended on the post).
After flashing custom roms, beats audio and etc via ADB, i believe my
battery stat display is not normal.
It would take at least 90~120minutes to reach 100% from 99%.
And sometimes even if I have the charger hooked up to the phone
it would still drop to 99% from 100.
I have two batteries (Stock and Anker) and tested them both.
It looks like no matter how long i charge it, as long as i have 100% or 99%
on the battery, it takes around 12minutes and 13seconds screen-on time to drain 10% of the battery. Which it was way less than i expected.
but after dropping around 68~63%, the battery seems to last longer on each
percent points.
On top of that, I think my phone is not charging anymore when I turn to power off. I can feel the phones gone cold and not charging, but the orange light is always on and never turns green for some reason.
So my question is:
IS THERE ANY SOLUTION (LIKE BATTERY CALIBRATION THAT ACTUALLY WORKS?) TO THIS? IVE READ SO MANY THREADS ABOUT THIS BUT NOTHING IS GIVING ANYBODY A CLEAR ANSWER.
I have the same problem as you. I'm on Sense 3.5 RC1.6. Infact I just restarted my amaze in hboot mode and then back into normal. My battery went from 10% to 60%. Then after like 15 minutes of usage it went back down to 10%. Also my battery drains to almost dead at about ~3 hours of screen time with moderate-heavy usage.
have you guys fully charged it ? gone into advanced in Clockworkmod and deleted battery stats?
i havent hacked my amaze but when i had my g2x after every flash i would charge teh battery to 100% then wipe battery stats x2 and then let the battery drain to 0 percent. then it should give you accurate readings
I did that but I used Battery Calibrator app from market. 2 times and discharge to 100%. Also how long should the battery last on average?
I'm runnign stock, it lasts me a day, but depends on usage. I text alot, some calls, twitter facebook, a lot of music, some FML, and some camera lasts me all day, (i charge in the morning so it lasts me a full 24 hour cycle)
Hmm seems as if my battery drains pretty fast. I timed it with medium-low brightness just leaving the screen on, with 3g and music. I get 1% per 3 minutes on. No auto-sync or background data either.
as most of people usually say i should fully drain my battery and charge til 100%,
im doing that right now.
My phone got shut off during my jelly defense stage 13 session
and plugged the phone but it didnt turn on for like 10 minutes.
so i kinda freaked out that the clockworkmod recovery that i have right now
does not support charging when the phone is not awake, but i guess the charging is really slow since i have finally turned on my phone.
im just gonna let it sit on my side table charging, and ill prolly fall asleep..
cuz im definitely not in the mood to watch LeBron James' face tonight.
I will let you guys know.
Thanks.

i hear you.
but after searching several threads about HTC AMAZE's bad battery life,
im slowly being convinced that 3 hours of screen time doesnt sound really that
bad. lol
mine just died around 2 hrs 45 min screen time while the phone was up without a charge for 14 hours. well i guess if i start using the phone nonstop after a full charge, then maybe ill get 3 hours or more.... but still...its only 3 hours...

Once it`s charged make sure you flash 5.5.0.4 recovery. Using the toolkit makes that easy.

ive overheard from someone that 5.5.0.4 is causing bootloops when flashing
other roms, but did you have any problem with this?

[Q] Battery dying extremele fast on CM9, any fix?

Before flashing CM9 to my mopho I had only used the stock rom, on Gingerbread my battery would last for 1.5 or 2 days, but since i updated to ICS it dies whitin 10~ hours of idle...
it usually goes from 100 to 70% overnight (6 hours). Recently I purchased Juice Defender Ultimate hoping it would help fix this issue, well... it did help but id didnt solve it, went from 30% overnight battery drain to 15-20% with airplane mode enabled in JDUltimate.. wich is ALOT from what i've read most users are getting (1-2% overnight, am i right?).
I've wiped my battery stats over and over (even tried the market app method) and nothing has changed.
I installed BetterBatteryStats and Watchdog from market, and both of them and the android battery stats show that "suspend" or phone idle are the cause of my battery dying so fast.
If anyone experienced anything similar and knows a way to fix this I would really appreciate it!!
Ive never seen my Photon go overnight with only a literally 1-2 percentage loss.. Not on stock, Cybiks CM7, or on CM9. but it usually only drains maybe 10 or 15 percent on higher end so nothing major. Talking ~8 hours off charger idle with random text or two and led going nuts blinking all night with data/wifi/bluetooth etc off but NOT in airplane mode. Are you on latest CM9 build? My bet is you have a random app screwing with phone keeping it from entering sleep mode or whatever its called. Check the "Awake" time under the battery settings to see if the awake time is allot higher than the "Screen off".
I have the same problem, no matter what kernel, no matter what cm9 build, still draining too much in idle. I know, others don't have such draining. But I give up and I am back on cm7, where everything seems fine.
I noticed that this happens to me as well. Previously, I fixed this by re-calibrating the battery. Now I was suspecting skype, but it is not causing this. I have noticed that having both GPRS/3G enabled and Wi-Fi drains power very quickly (about 4 times faster than having only one of those switched on). I'm using Photon in Europe in GSM network, so not sure is it the same with CDMA.

during night, "Awake" seems to be up about 50-60% of the time, a lot more than "screen on"
I´ve read that setting your phone to "never turn screen off" shuts down suspend process and battery actually lasts longer, has anybody tried this??
Are you guys logged into Latitude? I signed out of it yesterday and now after 10 hours on battery, although 6 of it was sleeping, I still had 86% left.

Thanks, I logged out already will report back after some time
I am not sure, but never logged in latitude myself, so I think, no.
And CPU was perfectly sleeping with turned off screen. But still the same draining. And what I know, it has nothing with gsm.
I as well am having the same problem, dropped from 88% to 72% within 20 minutes.
phone idles killing my battery at 50% any fixes?
try wiping battery stats in recovery with a full charge
