TF and dock battery log - Eee Pad Transformer Q&A, Help & Troubleshooting

Just posted this in another forum, thought it might interest some people here...
Hi all,
With all this talk about the dock loosing its charge and noticing it myself, I started a log on TF usage and battery. Started at 6am yesterday with a full charge in both. The TF stayed docked and turned on the whole time. From 6am to 5pm, the TF was on plane mode (I don't have wifi at work anyways) and the rest of the time wifi was activated. No special program was activated or deactivated. regular programs ran in background (email, splashtop, mynet, maps...) Here is the summary of the log:
6am to 5pm - about 1 hour and a half of use (moving icons and widgets, using catch notes, polaris and took 2 pictures), rest of the time the TF was in sleep mode. All the time in plane mode.
5pm to 10:30pm - Wifi activated, used continuously for 3 hours trying out Springpad, emails, tapatalk, watching a flash movie for 45 min.
10:30pm to 6:30am - Sleep mode with wi-fi activated.
6:30am - light is flashing and TF at 96%.
So, in 24 hours, the TF was:
Sleep + no-wifi = 9.5 hours
Sleep + wifi = 10.5 hours
Use + no-wifi = 1.5 hours
Use + wifi = 3 hours
The dock battery lasted for 24 hours with the TF never being shut down. This is with 4 or 5 hours of use. If we extrapolate, the dock+TF battery could last 48 hours with the TF turned on all the time and 8 to 10 hours of email/navigation use.
This is about 4% discharge per hour. Which I think is a lot since most of it was in sleep mode. Not very impressed with these results. Thoughts?
My feeling is that the dock IS discharging more than it should be. I undocked the TF with 92% of battery charge and will keep logging.
Tell me if you want me to keep posting these kinds of logs.
Joël.

TouchPro2 Battery Life falling rapidly :(

Hoping someone might be able to help me here..
Within an hour of being taking off the charger (and confirming it was 100% at that time) my battery life is down to 80%.
What's happened so far is:
1) alarm went off (set to ring only - no vibrate)
2) recieved 2 emails on yahoo (set to check every 60 mins)
3) received 1 push email through exchange/active sync
4) 1 calendar appt reminder.
The screen has probably only come on 3 times for no more than 10 seconds each time. My brightness is set to the 2nd lowest level possible. My ringer is on the highest.
Here are the apps I have installed. I have not "launched" any of these today.
.net 3.5
Easy Shares
Google Maps
Microsoft My Phone - (set to sync once at 3am & was on charger then)
Mobil manager for netflix
S2U2
Waze (another GPS app)
Phone is about 4 weeks old.
download HD Tweak and set up data disconnect after to 1 minute. I am almost positive your data is staying on after downloading email because i had the same problem with my Touch Pro. Keeping the data session open is a huge battery drain
My battery life is terrible too! I charge it fully throughout the night and the phone typically dies by the time I get home from work at 6PM or so. I barely use it at work. Never talk on it. The occasional text message. But by the end of the day the phones dead. I have no idea why. I know for some odd reason by phone will not automatically go into sleep mode. It should, but doesn't. Not sure if that kills the battery even though I manually push the sleep mode button each time.
I set up the HD Tweak software. We'll see if this helps. Does it work for the Touch Pro 2 also?
Any of you guys using a case with a magnet on it by any chance?
Possible explanation...

Just curious, did you charge the phone while it was on? If so, I've found it a problem. I once charged my phone while it was on, and I took it off after about 2 hours (the green LED indicator probably showed up an hour before I took it off). I checked the battery meter and it registered at 89%! I found out that there's a flaw in the way the found charges. Once the LED turns green for a full charge, the charger cuts off, but (I think what I'm about to say might be true) the phone thinks it's running something as it charges, thus causing the rapid battery drop.
Since then, I stopped charging my phone while it was on. I now turn off the phone and then charge it. I can last a whole day with about 45 minutes total on the Internet, and my battery would go to about 60+%.
However, as jaas666 pointed out, are you putting your phone near a magnet? The magnet tricks the phone into thinking the stylus/keyboard is being pulled out, thus causing it to wake up, which will drain your battery.
Have you tried a task manager to see if a program is running when it's not supposed to?
http://www.dotfred.net/TaskMgr.htm
I had terrible battery life and found two issues. One program was always taking up around 10% CPU usage (VZO video chat software). Also found that Google Sync, set up through ActiveSync, was having trouble. I'd open ActiveSync and find it in a synching loop. For me the solution was to untick "Tasks" in the sync menu. Since then, battery life has been great.

HD Tweak works fine on mine, I've also heard of some people using Diamond Tweak. I mostly text all day maybe some internet but I have gone a day and a half without charging and even then my battery had only gotten to ~20% so I think with a few changes it could be fixed. I'd check out some of the Tweaks threads here and at PPCgeeks for registry edits u can do to save the battery too
I had those issues with my 2000mAh battery on my sprint tp1. With my verizon tp2 my battery life is fantastic. I use the crap out of it all day also. Was wondering if the bad battery life is happening mostly with sprint users.
I have my active sync connected at all times for wireless email calendar task syncing. I charge with the phone on all nite long and the battery drains only slowly throughout the day. Less than 50% today. It is on 24/7 I never shut it down unless I'm soft resetting due to a file or app install. I use my ms3.5 task manager to keep stuff closed after using. I always put it to sleep mode by the button when I'm done with it. My screen is set to brightest and stays on 2 min. before sleep mode engages unless I manually do it.
I'm sorry to hear your battery issues, my tp1 with sprint was really hard on battery juice. I found it would struggle to find a signal alot, one reason I switched to vzw.
Hope you figure it out.
Sad to say that my less than 4 days old Sprint TP2 is disappointing to say the least in battery life and all around usability. Now i'm coming from a Treo Pro and so used to one handed operations and such. But i digress...
Battery life on this beast is sad, really sad. Someone alluded to Gmail Exchange ActiveSync as a potential battery drain so i might look into that. Basically i'm gonna hard rest and start from scratch applying less tweaks. Basically i find TF3D tedious really..takes too many steps just to do some basic things. I turned it off and managed better a bit but i just might go back to my Treo Pro and sell this thing..
My battery "appears" to drop quickly, but actually hangs in there quite nicely. My old phone only showed me 20% increments, so going to 1% makes it very noticable.
I ran cleanup first thing, then went back and customized.
I use Activesync in push mode (7 days per week 8am - 9pm), have it checking Hotmail, stocks, weather every 30 minutes. BT is on, Data on, WiFi off. I even went back and turned auto screen back on as I couldn't read cleanups default change in the sunlight.
Gets turned on at 7am, and at 10 pm I'm ussually 30-40%. Medium user - 40 minutes phone use daily, 1-2 hours total IE time, ALOT of email checking, hardly any SMS.
I do use a magnetic holster too. S2U2 fixed that issue.
Biggest drain I noticed is screen. If I turn off auto and go back to CleanUp default, I can get through almost 2 full days if I turn it off around 11pm, and back on 7am.
And as far as battery total use, my older phones always turned themselves off at about 15%. THIS THING WARNS ME AT ABOUT 4% and turns off 2-3%! That's alot of extra battery use.
There is a company making a 1750a battery that will fit in stock case.

7 hrs of Standby = 33% of Battery?!?!

Okay so I noticed my Captivate seems to lose a lot of battery while in standby. To test this, I left it unplugged when I went to bed last night. I checked the battery level right when I went to sleep and then again when I woke up...
My battery drained from 64% to 31% in about 7 hours!!!
I know other threads discuss bad battery life. A bright screen and a 1GHZ processor can cause this so I can understand why the phone won't allow me to browse the web for 10 hours straight. But is everyone else getting an almost 5%/hour drain in battery while in standby?
Here is a little info about my setup:
-I took off an animated background and put one that is relatively dark (Screen is off during standby so I would think this doesn't matter)
-I have WiFi and Bluetooth enabled.
-I use both wireless networks and GPS for location.
-I have 1 Gmail account setup to check every hour.
-I have the Daily Briefing set up to check every 3 hours.
-I have the Slickdeals widget set to check every 2 hours.
-I have the Latitude widget running (you can't set how often it refreshes).
-I have the ESPN ScoreCenter widget running.
That's about all I did that I can think of that can possibly affect battery. I know I would get better battery with less background widgets, but all of this is in line with the amount of background services I had running on my last phone (Tilt 2) and that thing would last for several days with light use.
So, what I'm trying to find out is whether or not this is normal behavior that everyone is seeing or perhaps if one of the background widgets I'm using is known for draining a crazy amount of battery. Maybe I need to hard reset the phone? Thanks in advance for any ideas on how to lock this down.
In poor reception I could see that. But I'm good area that's too much. Like 2% every hour is good... 5 is too much....
Thanks for your reply. I had 3 bars of service where I was last night. Also, this isn't the first time I've noticed about 5%/hour for standby, just one example...
So it sounds like I'm getting worse drain than normal? Now, how to fix it?
Well...with all the email checks and having various Widgets check for updates..it will definitely drain the battery. I have been able to easily get twelve+ hours on standby without GPS on and turning off wifi when not at home or in a place with wifi.
Definitely can't go days without charging like I could with previous phones like my blackjack II buy I can get 12-16 hours with light to moderate use and 10-12 with somewhat moderate use of Facebook, wifi, various other apps.
EDIT: the Bluetooth as well will drain the battery.
Sent from my SAMSUNG-SGH-I897 using XDA App
I have very similar battery usage to use. About 5% an hour not doing anything. I am always around a wifi and leave it turned on. I have nearly an out of the box setup. Between the poor battery life and crappy GPS, I may very well be taking this thing back.
Under Settings > Wireless and Network > Wi-Fi settings > Bring up the Advanced menu and set the Wi-Fi sleep policy to "Never".
This has helped my battery life immensely, since I am around Wi-Fi most of the time. This way all your data happens over Wi-Fi instead of 3G when the screen sleeps. I disable Wi-Fi when I'm not around any APs I normally connect to.
Pulled phone off the charger at 6:00AM yesterday morning. Streamed an hour and half to 2+ hours worth of Pandora over wi-fi getting ready for work and then some in the car. Did some web surfing during the day, various other things. (No phone calls really, except a brief wrong number). 4 e-mail accounts checking every 30 minutes (one an Exchange server). Also have Touchdown running push e-mail for another Exchange mailbox along with the Touchdown widget. Played around with some GPS apps (new google maps, Places, etc for a few minutes). Battery was down to about 16% by about midnight last night.
My phone charged fully overnight (with power off). Was turned on at 7AM, it is now 11am, and am at 90%.
I do not use GPS, have nothing running, no emails or social networking status updates.. The phone is on standby on my desk. I only do a few text messages and 5 minutes of voice calls / day.
So this means I get 40hrs of standby time? That is a little ridiculous.
I chatted with AT&T tech support and they said that the AT&T stores don't have battery replacements yet, but I could get a full phone replacement since I am within the 30 days still.
But from what I am hearing, it seems most people are having the same issue if not worse, correct?
I really don't want to set everything back up AGAIN. I am coming from using a Samsung Eternity - understand it isn't a true "smartphone" - but I use it the same, and would easily go 3-4 days without needing a charge.
with GPS off, wifi off, BT off, no data sync or background data turned on, i charge it fully at night -
last 3 nights in a row, at midnight it was showing 100% and at 7:30AM it would show 97-98% remaining, and that was using the alarm, set to loud and probably ran 2 minutes before i'd hit the off button
From 7:30am-11am, I have used 4% of my battery. I have these things going on:
-Exchange sync (real time)
-Facebook sync (once every hour)
-wireless off, bluetooth off, GPS not being utilized
-Weather.com and a Google search widget
The battery use shows this:
-Cell standby: 48%
-Phone idle: 36%
-Display: 8%
-Android System: 3%
-Email: 3%
-Android OS: 2%
I've barely used my phone this morning, so I'd think 4% of use in 3.5 hours is quite acceptable. It sounds like you need to make some modifications to improve your performance.
firehazard - what modifications have you done? I have wifi/bt off, background data off, no email syncing - display brightness all the way down..
To anyone who is having very poor battery life, I suggest a factory data reset when you exhaust other options. My phone wasn't lasting me more than about 8 hours on a full charge, with light to moderate usage. After a factory reset, I just ran nearly 24 hours with similar usage.
I can't tell you what changed or what got removed, maybe it was an app that was running and draining the battery that I didn't see, but battery life is MUCH better now. Hell, everything is running much better, even the GPS.
I went from wanting to throw this phone at a wall and return it for my iPhone 4 again, to loving it in less than 24 hours.

I'm referring to him running wifi and bluetooth when he's not even using his phone. Stuff like that.
Just for recording keeping, when a phone company says their phone can last XXXHours in Standby this means, that all wireless transmitters are off. this means (for the most part) airplane mode, with bluetooth, and wifi OFF.
these continuous wireless transmitters are why you didnt get the 200Hours or what ever it is in standby mode.
I recently took my phone back to BestBuy for a replacement since my battery was trying to kill itself overnight as well. I did the full charge when I first got it and purposely ran the battery down to quickly get it to turn itself off at 0%. Did a full recharge and repeated this process about 3 times and last night my battery only went down 3% over 6 hours. Compared to the 30-40% that was draining before, I'd say the full discharge/full recharge works that people have been talking about in the battery threads works. Thanks, everyone! I use Y5 to have it automatically connect to my WiFi at home when it's in range. Not much more than the usual was left to sync (although JuiceDefender may be working to turn stuff off when my screen is off) such as Gmail, Beautiful widgets, facebook, and one rss feed.
Either that or I had a crappy battery before
Seems like some folks are having the same problem as me, while others are having much better results. Firehazard's situation and drain while not in use is pretty much in line with my expectations of the phone. With my old Tilt 2, I left WiFi and Bluetooth on all the time and still got great standby time out of the phone. When those connections weren't in use, they weren't really draining my battery in any way. I'm going to try to disable them though and see if that helps. I'll also try to monitor the battery usage screen and see how much power is going to wifi and bluetooth when I have them on.
I've been suspicious of my battery as well, tracking it casually today.
Took it off the charger approx 8:30am, immediately went to 99%.
Watching it over the last hour it appears to be losing 1% / 10 minutes.

Just using it for the past 5 minutes to write up everything running has dropped the battery almost 3%. Albeit I have terrible cell coverage where I am. It does seem that the cell and wifi receivers are a bit weak, or the meters are biased conservatively.
*edit* I want to be clear that I love this phone, I just want to try and find out what and if certain services/applications drain the battery and if not then if I have a bad battery.
Okay, so I turned OFF bluetooth and WiFi and checked the battery before bed and right when I woke up. This time, I lost 24% over 8 hours. Certainly a big improvement over 33% in 7 hours, but also no where near where my old Tilt 2 was. I would lose 2-3% overnight at the most with that phone. I checked the battery meter and the majority of the battery went to Cell Standby and Phone Idle. Those don't seem like things that can be avoided through tweaking. I was in an area with 3 bars of service (same as night before), so I don't think that was an issue.
I'm debating whether or not I should try a factory data reset. Some folks reported good results with that. I really don't feel like reconfiguring my whole device if there isn't a good chance for improvement. Maybe the GPS fix that's coming will help battery life?
Have you tried reconditioning the battery? That would be the charging/discharching cycles mentioned throughout the forum?
I have done it and my phone has been on standby for more than 24 hours and I am still at 50% battery. It's just had very light usage. Wifi on for about an hour, snapping a few pics, deleting some others. A bit of calc usage. When I first got it, my battery was dismal.
Mine hasn't been modded one bit yet, just installed some apps from the market and a weather widget.
Yes, tried that. It actually helped a little but I'm still getting poor results compared to some.
I have another theory/question. I use gmail as my only email account on my phone. Its set up through the system and it syncs to the gmail application on the phone. I also have it set up in the Samsung default email client (which I prefer). Am I wasting battery because the two apps are checking mail independently? Does the gmail account sync while the Samsung one checks at intervals (I have mine set to 1 hr)?

3 day battery life on my D2G???

My Droid 2 Global is currently at 2 day 16 hours of uptime since unplugged, standard battery, moderate usage (some gaming, some phone calls, some syncing, some data connection, regular music listening)... and it still shows 40% of battery life left...
So, how did it all start?
I have followed some of the suggestions from the Battery Life Writeup thread
1. froze most of the bloatware in Titanium Backup (except for the Global apps)
2. set screen birghtness to Auto
3. set the battery profile to Custom
4. wifi and data disabled unless i need it, background data on
5. animation - all off
...
6. finally, i flashed the phone to a local CDMA provider, CDMA mode is set to Home Only, and 3G is off unless I need it.
7. i additionally killed and cleared data of the motorola services via built in android app manager
... but that helped only marginally, as I was getting 1.5 days max under minimal use
Until one day... I charge the phone in the morning, use it heavily throughout the day - music + data + phone calls... and it's dead in 12 hours. (( I actually shut off on me in the evening the same day during the phone call... I kinda got frustrated with this phone, since it wouldn't even last through the day when i needed it ....
... so I plugged it in while it was turned off, it charged fully, i unplugged the phone and turned it off before going to bed, now let the WTF begin :
WTF#1: So, I pick the phone up in the morning and it's still @ 100% after like 10 hours of standby (needless to say it usually loses 30% of battery overnight). I am like ok.... must be a batter meter lag.
WTF#2: I use the phone normally for the entire day - phone calls, music player + scrobbling via data connection, some syncing.. and by the end of the day the battery is @ 90%
WTF#3: I pick up the phone next morning after 1.5 day of use and it shows 80% of battery left At this point i start thinking the battery meter is screwed up on me and it will just shut off while @ 70% or something... but that wasn't meant to be.. I seriously start trying to get it discharged - playing games + wifi + syncing + putting in a sim card + checking mail + browsing... and by the end of the day it's only @60%
WTF#3 So, again next morning i pick it up and it's @ 40% of battery. and I have no clue how the hell this happened. right now its approaching 3 full days (2 days, 18 hours) of heavy - moderate use and the battery still shows 40% left.
Any ideas how this could happen? I will try to reproduce it once it finally discharges by letting the battery die completely and charging it while it's turned off. Anyway... your thoughts?
i got similar usage when i wasnt connected to a network i.e. data and wifi was off. i got a full 3 and a half days with minimal usage, turning wifi on when i needed it. with wifi and data on at all times i get about a day and a half of usage.
Plz let us know the outcome
I'm also struggling with batt. life
Sometimes I have to use three batteries per day
(I have many spare batteries just in case I have heavy usage)
It would be great to have three days of battery life!
Sent from my DROID2 GLOBAL using XDA App
Not sure how you managed the couple days of battery life, but that 100% after 10+ hrs without using the phone is pretty doable. Once you remove the bloatware that is. I can consistently let the phone sit for 10-12hrs and it will at most lose 10% battery life.
If you use your SMARTphone as it was designed, there is no way to get that batt life. If you use it like an old dinosaur nokia(phone calls and texts only no data) then sure, that is possible.
sent from a blackANGEL
Hi guys, just stopping by to update that since my original post I went through a couple of charge-discharge cycles, always getting 2-3 days of battery life, depending on my usage.
So, as you see, it's possible to get this kind of battery life if using the phone as smartphone cause well.. that's what's happening to mine
I will add the additional details I omitted in my original post:
------------------------------------------------------------------
1. set your default launcher to LauncherPro
2. follow the steps in the Battery Life Writeup thread if you haven't yet
3. turn off wifi and data unless you are using it
4. clear your battery stats using Calibrate Battery app
5. discharge your phone completely until it dies (if you have a wall charger)
6. charge it back up while turned off, turn it on once done.
7. force stop & clear data for the following services - (proceed at your own risk lol it didn't break my phone but it might break yours )
- Task Manager (freeze it)
- Bluetooth Share / Bluetooth Dun (if you don't use bluetooth)
- com.motorola.photowidget
- Email Engine (if you don't use email app)
- Home (if you use launcherpro)
- Motorola Services
- Social Messaging Service
- TTS Service (if you don't use tts)
- Voice commands (if you don't use voice commands)
Then, theoretically you should have the same battery life as I do.

[Q] Battery life of Galaxy Note 10.1

I just got my Samsung Galaxy Note 10.1 (GT - N8000) as I observed, I only got 8 hours in my first recharge, then 2nd 12 hours, 3rd 13 hours and 43 minutes.... It seems like a get a really short battery life.... I only use it for browsing the web (chrome), playing some games (temple run, pitfall, beach buggy and more), and flipboard..... My brightness is set to Auto, Power Saving is on when I reached 10% and my SIM is active but mobile data is off... Is there something wrong with my tablet? Thanks in advance for the reply! :cyclops:
is that screen time? or does it drain simply sitting idle. I get about 10 hours of up time for the screen. sometimes don't charge for 3-4 days if I'm not using it much. btw mine is WiFi only, are you roaming or searching for signal often?
Use power save mode if your doing light browsing ect. 8to 12 is what you can expect from a tablet. Screen time that is.
Samsung Galaxy Note 10.1 - Battery Life
The key here people is the brightness setting.
I personally get 5 hours 30 mins screen time on Full Brightness with Wi-fi & Mobile active, not using Power Saver.
With 15% battery remaining, never run your lithium-iron battery too low, can shorten the life span.
Here are some other peoples figures:
(8 hours and 15 minutes - Continuous Video Playback, Auto Brightness)
In practice, the slate lasts a bit longer than 8 hours and 15 minutes with continuous video playback, and anywhere from 8 hours to 9 hours and 40 minutes with more varied usage (smaller video games without loads of graphics, web browsing, e-mails, photo editing and some video).

(8 hours plus - Mixed Usage - Power Save Mode)
In a single charge from its proprietary cable, the Galaxy Note 10.1 with its 7,000mAh battery should last you all day. In a mixed scenario of browsing, video and productivity, it lasted us well over eight hours, though that was with the Power Savings setting activated.

(5 hours 17 minutes - Continuous Mobile Surfing - Suspect Auto Bright)
(8 hours 57 minutes - Continuous Wi-fi Surfing - Suspect Auto Bright)
The Galaxy Note 10.1 for Verizon lasted just 5 hours and 17 minutes on the LAPTOP Battery Test (continuous Web surfing over 4G LTE). When we switched off LTE and ran the test over the Note 10.1's Wi-Fi connection, battery life increased to 8 hours and 57 minutes.

How to schedule WiFi on/off every 10 minutes?

Dear all
I would like save battery life on WiFi. Is there a way I can schedule WiFi on/off at certain interval? Example: Turn on WiFi for 1 minutes then turn it off for 10 minutes and repeat these 2 steps indefinitely.
There are several automation apps on the play store that should be able to do this but using an automation app will cause you problems. The problem will be that when you want to turn it on for an extended period of time it will turn off at the next interval, so you might be in the middle of something and then it turns off. Have you looked at how much battery your WiFi is using? Settings>Battery>(and for me I touch the battery at the top) It shows my battery usage, charging spikes, how long it's been since a full charge and below that everything that is using battery and at what percentage by group. i.e. Apps, Mobile network standby, System, Phone idle, Bluetooth and WiFi. My WiFi is on 24/7 and is currently sitting at 0% 6 hours after being taken off the charger. Just saying. Tasker is probably one of the best automation apps, but it's a paid app and has a bit of a learning curve. There are some that are simpler for free that will likely work.
