X10 Power Usage

Hey.
Got my X10 a few days ago,
And im the only one with a power problem ?
Having to recharge it alest once a day ?

My batteri drops aprox 12 % per hour, so I usefully charge 2 times a day.
Since 1AM to now (12AM) it went from 100% - 24%. And Ive been sleeping alot, so the phone hasent been muched used either.

What kind of usage are you partaking in? In my experience most smartphones have to be charged daily.
Here's a post from Esato Forums where someone did an extensive battery drain usage test:
http://www.esato.com/board/printpost.php?post=2933402

The last day Ive been using it minimally, and Im on my second charge for the day. All my other phone last 1 day (6am-12pm) before needing charging. But my X10 needs an aditional charge at about 2-3pm..... And even then is as good as empty at 12pm....
I hope its just a small software bug, or something that could be fixed with a reset. Im starting to enjoy this phone, but there are several days a week, I will not have the time to charge it a second time..
Think Ill go for that reset, and see if that helps....
Anyone else with X10, and batteries that drain extremmely quick?

Mine dies after about 8 hours, but this is usually normal with new batteries, it should be better after a few FULL recharge cycles.

Were your previous phones smartphones, just out of curiosity.
Also, you could try to reduce how often TimeScape polls in the background for updates. That might help.
My current iPAQ 910c lasts a full day if I do nothing but the occassional phone call and SMS. However, if I do anything power intensive the battery fails, and the phone is done until it can get 2 hours or so of charge. But that's why I'm looking to replace it... definitely not normal.

I have access to every phone I want.. And Ive only been using smartphones.
(Currently as in sign.).
I dont use timescape or mediascape, so they have been disabled.
And yet the battery only last for aprox 10 hours....
I never had a phone with such a bad battery, however, Ive never had a phone with such big screen or cpu either....
You gain some, you loose some.
And to he who talked about recharging cycles to maximize battery,
this kind of batteries dosent work that way... They are allready maxed..

I've had mine for a few days now.
The battery's pretty good, I've only charged it once over about four days, so I'm pretty pleased. However, it does seem to use a lot of power if you have wifi on, even in sleep mode.
I've also had no problems with my "a" in either keyboard (Norwegian/Japanese) so far.
I'm still on 14 btw, if anyone's noticted battery dropping after they updated.

I would not say that the my battery is good. but it is ok, i haven't had it fully charged yet, since I did get git yesterday. and it did last about 10 hours or so, from 60 or 70%. with playing music, trying out some things etc. but I worked 5,5 of these hours and was in the movie theater 2 of the other hours.
anyways, I haven't really had much problems with the keyboard either, as you said. the only thing that really buggs me is the damn space button. it is too small! :/ I wen't from an X1 to the X10 no, from using HTC magic before that. But I am starting to get really used to the other keys.
I haven't installed the latest build/patch either.

Just download "spare apps" and see what apps som drain u battery
My X10 take only 6% on 3 hour on normal use

very very bad battery drain! Left mine on flight mode at 2AM with 50% battery left, before going to bed. Woke up at 11AM and the battery was dead with no usage nor cell connection!

A chellphone uses more battery when there is bad reception, because it tries to get a better reception.
Like if there is just edge, the phonei strying to get HSDPA connection instead, this drains more of the battery.
+ With android the phone leaves some of the apps running in the background.
I recommand that you get an app that can shut these down.
Like a task manager kinda..
eg.Advanced Task Manager
I hope this helps ye.
and if you go into "settings - about the phone - Battery usage" then you can see what apps that is draining the most of the battery etc.

As I wrote before, phone was in standby on flight mode: it means that NOTHING was running nor any 3G data was exchanged. I've had many Android phones (Magic, Hero, Milestone, Nexus, Legend) and in similar conditions they lost only a couple of percentage points of battery, not 50% like X10!! I do love this phone, but heavy battery drains is driving me crazy (and it's definitely not a faulty phone, since I know many many users with the same problem)

I actually think the battery is good too. I recharge every other day, which seems to work fine.
I have bluetooth and wifi off, and mostly doing manual updates for timescape. I do surf quite a bit though, and no problems with battery drain. In my experience, my X10 lasts a lot better than a Satio for example.

Strange how half of the people posting here, have very good batteries (1-2 days), and the other half have extremmely bad batteries (8-12 hours).
I doubt the ones with the bad batteries are "worse user" then the ones with the good batteries......

I'm one of those with lousy battery usage. Hardly use the phone, but drains in no time. However I've ordered 4 new batteries, so gonna test all of them and see if there's a pattern.

Grrr.. Was just setting up my contacts to Facebook.. Took around 20 minutes and drained 21% of my battery.. That's just not okay..

I just left it for 2 hours without doing anything and the battery from 90% dropped to 65%. This is not cool at all. SE we need a solution ASAP.

I'm one of those that get bad battery duration on the X10. I usually leave BT and WIFI on as I did in my N97. By observing who drains most of the battery, I get around 30% for the radio in standby and 20% for BT. The processor is only a small percentage (2%) so I don't belive that the snapdragon cpu can be blamed for bad battery duration. How is it possible that Nokias as the N97 having the same communication hw (GPS, WIFI, 3G, BT...) last for days with similar usage and battery capacity? Ok, the procesors are ony half the speed but I don't belive this makes so much difference...
I own a HTC Nexus also and has slightly better battery duration than the X10 but way far form the N97. I've roorted the phone and can change the CPU speed. It makes very little difference on battery duration if you set 400 or 300MHz instead of 1GHz.
So, it seems what makes all android devices so power hungry is the way the OS handles the communication interfaces, I belive most RF chipsets should have similar power drain and CPU's are idling most of the time. Perhaps symbian has a smarter algorithm to hanlde 3G/GSM/WiFi switching and no services polling the network when the phone is in your pocket.

So seeing i am in an area that does not have 3G I will have a problem with battery drain bcuz it will be constantly be trying to connect to HSDPA?

SGS Bad Battery Life? Share your experience

I think the consensus is that our Galaxy does not really have a "good" battery life. But how bad is it really?
Can you share your experience with regards to real life in terms of % drop during active use and non-use? (pls dont give built in battery stat/usage which I think is pretty useless for comparison)
Pls try to keep to following format so that readers can gauge their phone battery life:
===================
Phone: SGS I9000, DXJG4, voodoo lagfix 3.0, non-root, 3G+background data+Sync(gmail)+Location(wireless)=ON, BT/GPS/Wifi=OFF, auto-brightness, live wallpaper, Friends+weather+stock widgets update hourly.
Stand-by (overnight): 1.46% drop per hour (i.e. approx 12% drop over 8+hrs)
Active use: 23% drop per hour (3G web surfing with Opera Mini)
===================
Phone: Iphone 3GS, 4.02, non-JB, 3G+Push/sync(gmail)=ON, wifi/BT=OFF, auto-brightness.
Stand-by: 0.7% drop per hour
Active Use: 19% drop per hour (3G surfing with Opera Mini)
====================
Phone: HTC Touch HD (WM6.1), 3G+PULL gmail (15min)=ON, wifi/BT=OFF, auto-brightness, Sense UI (all widgets manual update)
Stand-by: 0.9% drop per hour
Active Use: 25% drop per hour (3G web surfing with Opera Mini)

The problem with this, is that batteries aren't equal, some people are using possibly counterfeit batteries, and some people batteries might not be calibrated.. Maybe it would be better to run the battery down to 0%?

if having issue with your battery and your rooted just run the command to remove /data/system/batterystats.bin then the reboot command with ADB it will improve your battery big time... this should be done when the battery is low like 10%..I did this and it took it from 10% to 38% and I got almost a 1/2 more out of my battery..
when ever you flash Roms you should clear the batterystats.bin.. when you reboot the android system will make a new file.
Code:
adb shell
su
rm /data/system/batterystats.bin
reboot

Just to set up the expectations here, its not always that clearing the battery stats work.. its just a history of the usage anyway.

depending on roms etc.. i had from 1% / hour issue battery drain to barely 0.3% per hour drain both in idle / stand by of course (it lasts forever on JPK in 2G on standby for example)
don't know what really causes the 1%/hour bug
in use i couldnt tell but i feel like it uses more than other phones unless you're watching black ^^

Apple has really good standby battery consumption on all their devices but SGS Probably has among the best battery life during active use.

I know it is quite the "norm" to have a 1-2% per hour drain on standby with 3G and sync on. I had the same drop using JF3 and the later JG4 firmware. There is no diff before and after lagfix.
I am not too bothered about standby drain but I am quite unhappy with the active use drain of 23% per hour.

If by active, you mean typically a form of internet or communication a lot of that blame goes on the application and consumer, we can't have high expectations for battery life from a 4.0" that is producing white backgrounds. A comparison to a 3.5" device that uses an LCD screen is just flat out unfair, there are other devices that you could compare to, say Droid X, which will also have better battery life, but that also doesn't really give more of a right to complain.
I'm surprised that there isn't better access to white on black internet reading, much like how the e-readers are set up. Is there nothing, does dolphin or mozilla have anything like this?

Right now I'm using 10% per hour using it as Mp3 player. Thats what juice plotter tells me. Using OCLF ontop of Voodoo lag fix under JM8 . I'm going to flash JPM tonight and just use OCLF as Voodoo isn't working with Froyo YET. But seriously the phone flies but battery life is unacceptable. When I use 3g to browse its like 20+% a hour minimal. I blame lag fixes as voodoo is known to kill batteries

battery drain
Wow! yesterday when I went to bed I had 72% full battery on my new galaxy s and this morning I found my telephone dead with 0% battery. the phone has standard XXJM1 firmware the only thing that I did is rooting. Yesterday I have installed Navigon, Igo, and Timeriffic on this phone, I also have setcpu running there. There were no issues before yesterday though, so I assume setcpu has nothing to fo with the problem. Any one has similar issue?

Well I don't have anything like your setup (jm8 + voodoo-oc + doc superslim here) but I believe I was experiencing a similar issue and it was not related to voodoo (checked the indicators listed on project-voodoo.org)... Maybe that is setcpu. You might want to try that because I have none of the other apps you listed.

I recently experienced similar issues and found out about some apps that prevented my phone from going into standby state or constantly smoking CPU time. Those were Tango and SwitchPro Widget, I'm not sure about Skype. Uninstalled all of them and now everything's fine again.
I suppose you have issues with apps gone crazy, too, as a battery drain to this extend is very unlikely to be caused by a lagfix or something like that. Suggest you uninstall recently installed apps one by one and see if the situation improves. If you have some 3$ spare, consider buying SystemPanel -> hxxp://goo.gl/aUxO which does a great job of monitoring your android system for CPU huggers.
Please share your experiences.

I also have thoughts about SetCPU and I revealed another problem - I setup profile in SetCPU for screen off event to limit CPU to 200Mhz and turn on powersave mode - this caused my phone stuck in sleeping mode, only battery-out would solve the issue, I have corrected this profile to 400Mhz-200Mhz and conservative mode, so far no second issue. Will see after overnight.
Well, the battery on Galaxy S goes very fast, will look for other solutions to longer battery life. I want it to be at least 2 days.

bs
i had voodoo with 1% battery drop in standby fresh install data wipe
i had voodoo with 0.2% battery drop in standby fresh reinstall data wipe
Didn't find out the difference
the truth is elsewhere
Let's see how it goes in froyo.

I had some high battery drain issues with the 'root' part of OCLF. I uninstalled it and installed voodoo and it seems to have gone away now. Battery life is definitely a little better than my Desire.
Btw, someone mentioned running only on 2G. How do you do that? I havent been able to find any option to disable the 3G radio (messing the apn settings doesnt turn off the radio...does it?)

my opinion
SGS is the best android phone because of battery.
compared to desire sgs holds 4 times more when surfing the web.
i allways foget to disable gps, wifi, i use full screen light. and it holds 40 hours always. im realy happy with that. had g1 before and the best was if it hold from morning to evening, but if much of use it lasted in 4 hours.
my frien has desire. he disconnects charger in the morning, and connects in the evening.

i need 2 battery a day, if i don't top it up when i by my PC/laptop/car

I'm really curious on how you manage to have 40hrs battery life. My SGS only have 18hrs tops, and that's with what I classify as conservative usage. Most of the time it only lasted 12-14hrs. So please do share some tips and tricks if you have some
( oh, I've set the screen to the lowest brightness setting, I don't use live wallpaper and use a dark colored wallpaper to conserve battery)

Battery life issues.

I know there have been many threads like this but I'm just looking for clarification as this is my first Android phone. At my house I usually get the Rogers H speed with 3/4 bars. When I browse the Internet for just an hour, 15% of the battery has been drained. Is this normal on these speeds?
I plan on leaving an IM client on 24/7 and using GPS/maps daily, so I am a bit worried because this may not last the entire day. I could switch to EDGE when I don't need it but apparently I heard that will disconnect once I start a voice call (and want to keep my IM on always). I checked my battery stats and apparently the cell standby (H) is taking most of the battery.
I am using CyanogenMod 6.1.1 with stock radio from Bell. I'm going to try to see if SetCPU makes a difference. And is there any program that can limit the HSPDA bandwidth so less battery is used? Thanks.

call *#*#4636#*#*

If you are at home or in a Wi-Fi accessible, Turn ON wifi - it uses wayyyyy less battery than the phone radio when it comes to Data....
you could get a extended battery.... Mugen Power has one for 1800 mAH and its the same size as the stock battery so no need of a bigger door.

What is your screen brightness set at? The screen is one of the top battery drain culprits. Try turning off auto-brightness, and turning the brightness down to as low as you find tolerable (depending on personal taste, and the lighting conditions in the places you use the phone the most). I recently just lowered my brightness to 35% (still plenty bright under many conditions) from 45%, and already noticing a significant improvement in batter life. Battery usage of the display dropped from over 70% to 45-50%. I haven't had the brightness set this low long enough to see how it translates to hours/days between charges, but we'll see how it goes . . ..

my battery life is retarded. probably less than yours. i swear i think i lose 1% of battery per minute of web surfing. battery is fine if you do not go on the web and have 2g on all day.

Yeah, it's pretty bad.
But that's the same for most smartphones nowadays I think...
Back to the days of game gear, the battery muncher.
6AA = 5 hours of gameplay.
I just bought some Chinese 1500maH batteries on eBay and I don't know if they're actually 1500maH. If I play with my phone a bit, I get 50% after 8 hours at work. Yikes!

Assuming the screen was on the entire time, 15% drain for an hour of web surfing sounds pretty good to me. The main battery eater while using the phone is the screen, so I doubt messing with your connectivity is going to drastically change your battery consumption in this usage scenario. Changing connectivity to Wifi or EDGE would probably help more during those times when your phone is off but your phone is still connected to the internet.
On a side note, I had terrible idle battery life when I was using CyanogenMod 6.1.1 on my Desire Z. When I was using my phone, battery life seemed normal. But when the phone was on standby, it seemed like my phone was running even when it was supposed to be on standby. I suspect it might have been SetCPU constantly polling in the background. I switched to Virtuous and didn't install SetCPU/didn't do any overclocking and my life improved literally threefold.

[TIPS] Juice Defender, Why its good and bad

Reading through threads I see lots of people saying JD and similar apps are good and lots saying they are bad. This is quite confusing for someone who just wants to get good battery life. In my experience I have gone from finding it good to finding it bad. I will try and explain why this occurs so that people are able to decide if it will be worthwhile for them.
First install Battery Monitor Widget and find out what sort of drain your battery is experiencing every hour.
With a stock rooted G2 with data connection on continually (no wifi) I was getting around 80-150 mA which explains why it would not last longer that about 16 hours. Most of this drain seems to occur from data connections. After installing JD or something similar the drain can be reduced to around 50 mA. Which is great, suddenly you get the claimed 1.5 to 2x battery life. JD seems great.
But after you install a good ROM and custom kernal, remove or freeze all the apps that keep using your data connection unnecessarily and install Better Battery stats you observe that JD stops the phone going into a proper deep sleep. If you dump it the drain on the phone drops to very low numbers usually under 20mA sometimes 5mA or even 2mA. This means you use around 1-3% of the battery life of the phone overnight with no changes. Now your phone can last days between charges. Note this is with Data or Wifi connections turned on and Sync active always.
Summary:
On a badly set up phone JD improves battery life (for the lazy)
On a well set up phone JD worsens battery life (takes some time)
Note: I got the best results using Speedmods kernal but I have no reason to think that other kernals could not get similarly low battery drains.

Thanks for sharing your observations. I have juice defender and have had similar findings. The wake locks jd causes play into the aos bug of the phone which is why it can make things worse on a well set up phone (the extra drain from the wake locks outweighs the savings from turning the data connection off when it's not in use). If not for the aos bug it would probably be good in all cases. I had noticed this in my testing and am glad to see I'm not the only one.

Thanks for sharing your observations.
If I had seen your post much earlier than I wouldn't have to buy JD. Anyway, I have gone through the hard way, and learnt how to keep my phone organized and minimized rouge apps issue. JD is pretty much useless now.
IMHO, I think Battery monitor widget pro seems to be a much better buy

Thanx for this helpful info!
BTW, kernel not kernal

I do not have a lot of widgets and sync as little as possible. Mail sync is only on demand (when I have time to read it), and Weather is every 6 hour (disabled in night time).
So my battery live is good ½% standby and with normal use it can easily last a full day (no gaming, just Internet, Talk, SMS).
I decided to try JD in order to save even more juice, but JD ended up using more battery than it saved me!
So I can confirm that JD is good for the "lazy user" and bad if your aware of your sync. and how your apps behave.

What do u mean by dumping? You said if you dump it and the drain goea away? Im a bit confused

By 'dump' I just meant uninstall JD. If you uninstall JD your phone will be able to deep sleep properly provided it is set up well and you actually save more battery.

Sure you can do that, but it's not necessary. I leave wifi and 3g on and still have drain of 5mA all night. I wake up and have lost almost no battery. The same applies for when the phone is idle during the day.

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Xiaomi Poco F1's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!

Considering the total capacity of the battery, that strikes me as a bigger drop than I'd be used to, particularly with a virtually brand new battery - anyone else?

I've never owned a phone running MIUI but I understand it has pretty aggressive power management (shutting down services and relaunching them when they're needed, rather than just letting Android's power management do its thing in letting them sleep). Wondering if battery drain might be a MIUI-thang?
Does anyone have any first hand experience to improve on my rumour-based speculation?

That's because your phone was awake all the time because of wifi on all the time. Phone didn't go to deep sleep.

That's a weird battery graph you have there. Even though screen was off, somehow you phone was awake non stop without a break.
Below is my battery graph. When screen is off, 99% time phone won't be awake. But I don't know much about that stuff.

i don't think its due to the wifi. check your apps usage/battery page. some app is draining the battery. just close all apps and reboot your phone.

The battery usage of all the apps seems to be normal but Android system has pretty high usage of about 20percent
In the image below it can be seen that that the battery drain is present only when I keep the WiFi on.

besides android system, what other apps is listed there? can you show the apps usage screenshot?

I'm also getting quite high battery drain at night (around 13%), I have really few apps installed and I tried closing all the apps in memory before going to bed. I haven't tried turning wifi off but that shouldn't be the issue in a modern phone. I hope it gets fixed in an OTA. Otherwise battery life is great.

I tried factory resetting the phone but the problem persists.Ill post the usage when I have used it for some time.
I noticed another thing that this problem is only present for specific WiFis. It works just fine for other networks and also in the networks where the problem is present there is a constant network traffic of about 20-30kbps

Don't think there's going to be any OTA for that. Only few people facing the issue. I get like 4% drain over 12 hours and I'm sure that's due to random notifications waking my phone during sleep. Thats normal.

Nobody tried BetterBatteryStats? It should show what is draining the battery.

Had a really bad stand by drain from about 85 to 63 percent because of Wifi
Turning WiFi off solves the problem

I too have this issue, my battery drained 20% with the screen off + WiFi ON for 7 hours. My graph was almost the same as yours, even though the screen was OFF my system was awake.
Today I checked the same by turning OFF WiFi, there was only 2% drain.

0.5 percent/hour in case WIFI is off
1-2 percent/ hour if wifi is on
In case of poor network reception 2.5-3 percent/ hour with wifi turned on

2% to 5% drainage at night.
The battery drains 2% to 5% at night. Well yeah , it doesn't makes sense while the battery is 4000 mAh , I tried removing background app but still something sucks the battery. I'm new to MIUI , might be the case with this operating system or is it due to always on fingerprint sensor?? I would like to disable that feature because I am I'm love with face unlock. It's just awesomeness!

..

In last few days i am observing, my battery drained max 2-3% in any given night.
I kill all apps from recent menu before goin to sleep. I never turn off WiFi.
I feel its quite impressive for my usage. Lasts me whole day with 20-30% remaining. I get SOT of min 7hrs before battery hitting 10%.
If anyone of you facing major battery drain, try using battery saver. It turns off sync, turns off gps/location. You can even schedule it if you want.
In my case with battery saver on, my general usage is unaffected. Bettery lasts 15-20% more. I even play PUBG at full settings with bettery saver on and it doesn't drop a single frame.
