Battery Life

Hi
Had my phone a little over 24 hours and I may have a very poor battery
I have a LIVE screen on the one with the water and the leaves plus, I haven't made or received any calls but I have used it a little for internet and a few text messages
The green bar was on full about 5 hours ago and if I had to guess how long my use has been I would say 30 mins in total of the 5 hours, now my battery is indicating less than half full
Imagine if I was out all day making and receiving calls?
Does this sound normal?

This is normal for the first week or two , the battery is adjusting itself to your needs

It's absolutely normal and you'll really notice a difference in about ten days, a couple of weeks the most.
That said, live wallpapers do use more battery. I much prefer a static dark one

adding to that make sure your phones nicely drained before recharging to ensure you get a nice full charge for next time... i took my desire's battery at least 5 days to start having a long term charge

bettery
same here took a week also what really helped me is having advanced task killer and setting it to kill unwanted apps after i lock the screen

i dont think you should use task killer, the apps will end them selves, i used task killer and got alot of force close after and errors etc
however force stopping unwanted applications is also good.

5 H 55M 55S unplugged, hahaha no joke its all 5's
and now my battery is almost dead surely this cant be right
has anyone ever been given a replacement battery for their phone or do they ask for the phone to be returned if this is infact a fault

Battery sucks, phone is power hungry. Get used to it
I've had 2 desires since a week after it was released, i can count on one hand how many times I've got through a day without plugging my phone in.

I get about 2 days on my phone if I don't mess around with it a lot or get many calls. I normally plug it on overnight. Every night.
Nowadays that seems normal for a smartphone. Personally I think the battery life is slightly better than the iPhone 3GS.
Angry Birds means it lasts about 4-5 hours...

It's all down to how your using your phone. If you have a live wallpaper and many widgets and apps that run in the background like running in the notification bar, then yes, your phone will die pretty fast. Also it depends on how much CPU your burning. When I first got my Desire, I was like WTF. This is useless battery life and was starting to play hell. Now it's fine. I can leave it for 2 days easily if I just text or flick through settings. It just depends on what your running.
BTW, no one should have a task killer. It defeats the purpose of Android. You can get a lot of force closes and other things. Just leave them alone and let the OS handle the apps. Android does end the process if it's idle, eventually, but it's not using anything really other than a bit of memory just to keep it going a little.

As GoogleJelly pointed out, it really does depend on what you do with your phone and what's apps/processes are running on it while the device is using battery. Even I found the battery life pretty poor at the beginning...I found it quite annoying having to charge this thing nearly every day.
After some light tweaking, I managed to get the battery life to go over 3 days and I now have no reason to complain about my phone Mind you, I'm not a heavy user....As for background apps, I think i've got about 5/6 apps running at a time...
EDIT: I've attached a screenshot of my battery meter.....

What app are you using to view your battey history?

I also tested task killer when I got my phone. I thought it was fixing battery life, but after bedding the phone in a bit I took it off to see how much difference it would make and I didnt notice any difference at all...

I configured Quick Battery app to go to battery history from my phone settings every time I tap on it. You can view your battery history through:
Settings > About phone > Battery use.
If you want the graph, just tap on the top layer which shows the length of time you've been on battery.
EDIT: This works for Gingerbread based ROMs (it's the standard feature lol)...can't remember this being on Froyo.

This is irrelevant with Li-ion as this is a myth from the ages of NiMh batteries. Your battery will not get ruined if you don't discharge it completely before first charging.

Ah right, cheers for that. Didn't know it was all built in

One of the main reasons why new smartphone owners experience fast battery drain lies in the simple fact that they fill up seven homescreens with widgets that sync over mobile internet every hour or even more often, which really kills the poor juice like a massive gas leak.
After about half a year of use I've reached a stage where I use just 2 screens on my Desire (CM 6.1.1), of which page no2 is a full 4x5 agenda and Page one has just one actively updated widget (home weather).
Combined with restricting network usage of random apps by means of DroidWall and underclocking the processor at certain parameters (eg. battery <50%) the phone lives for 2 days pretty easily, with moderate browsing, music etc included.
But TBH I've really decided that the battery usage is absolutely random because some days it just drains like there's no tomorrow with no apparent reason that I've been able to identify. Carry a spare microUSB wire tbh :/

I read so much myths in this thread concerning Li-Ion batteries.
First of all Li-Ion batteries do have instantly the capacity they are intended for. Even 5 charges won't change that. The only thing which can change over time and charge-cycles is your phone recognizing a new voltage level as "full" (read more: "calibrating htc desire battery") or you playing less with the phone or having power-consuming apps uninstalled.
Also a full first charge is not necessary. This "requirement" are from past days with NiCd or NiMH battery-types.

The calibration during the initial week or so of using the phone arises from phone-side calibration, not the battery itself, which is why deleting battery stats from recovery can at times resolve battery issues :V
Phone didn't last half a day after flashing CM 6.1.1; after a couple of days I charged it to 100%, deleted the stats and voila, it's about as perfect as a terrible smartphone battery can get.

[Q] Battery consumption: I need your help for a comparison

I found a very good program for my Motorola MB525 (Defy) for monitoring the battery draining from the market.
It's name is Batery Monitor Widget and it's free.
With 81% of battery it says only 7 hours and 16 minute left without doing anthing!!! The data is on and Wi-Fi connected to my home network.
Is it normal?? In the night in airplane mode after 9 hours it drain 8%-9% of battery. Again: is it normal???
If you can try this application and report your results...I think there is some application that drain my battery!!
Thanks!

Not really a comparison here, just a little story.
Yesterday i screwed up my Defy playing around with some rom. Nothing terrible, but i had no time to re-flash another rom, i had to go to work. So, i pickep up my old SE xperia x1.
After an entire day, 4-5 calls and several sms, that phone drained less than 10%. Then, last night i put the x1 in stand-by, well, that was a real stand-by, no power consumption at all.
Now i'm back to Defy, 2 hours, 15% drained...
All this just to say android is amazing but terribly hungry of power, even when the screen is off, even when airplane mode is on. I don't need a comparison to know about it
EDIT:
you said your wifi was left on, well android is hungry of data too. Even if you do nothing while wifi is on an amount of data still flows, sometimes i can see several mb downloaded by my Defy in a few hours, but no real usage by me. This also contributes, you should try to turn the wifi off or disable background data when you don't need it.

In standby (3g, sync only calendar and contacts) I have 1-1.5% battery consumption / hour. I think this is normal
With my normal usage i have some 20-40% left at the end of the day... also Ok.
WIFI on & connected will consume a lot of battery so I am not surprised.
BTW I also had an Xperia X1 and the consumption was roughly the same as the Defy... In fact more than 1-2 days on a charge I very rarely had on any of my smartphones with normal usage.

last week I was working in the forest for a few days with no signal at all, so I turned on airplane mode: I remember it going from 45% in the morning to 42% in the late afternoon!
(with everything turned off, just used it occasionally to have an idea of what time it was)

It's ok to be an android fan, i like it too, as i said it is amazing. But, battery life is definitely NOT the strong point. I can compare the two phones now, at this moment. Honestly Defy's battery life is a lot shorter.

what's the other phone you compared?

I really don't have problem with Defy's battery life. As far as my memory serves, all cell phones I ever owned (7~8, all nokia, se, moto) could standby (just standby and don't use at all) for a week or made around 5 hours call. In my case Defy can also standby for a week or allow 5~6 hours usage.
I'm on a 2g network (probably helps alot), as I have wifi at home and at work. I have an exchange email, a gmail, 2 yahoo mails, and a weather app, all allowed to sync at default settings. I don't have facebook or twitter. GPS and bluetooth are enabled only when necessary (occasionally). I overclock Defy to 1000Mhz with SetVsel, and underclock to 300 when screen off. With conscious observation over some time, I find that 1% battery is consumed around every:
- 2 hours standby with wifi off; or
- 1 hour standby with wifi on; or
- 3~5 minutes usage (calls, emails, surfing,...)

thats some amazing battery life u got there abc ...what rom are u using?

hey guys, just a quick question. with which setting do you think i'll have longer battery life: 800MHz/58vsel or 1000MHz/56vsel? btw, i got my phone stable at 800MHz/45vsel

I was using the orange 2.2, and am using the finland 2.2 now. Both have similar battery usage.
But I have uninstalled some stock applications which I don't use but keep running in background, like BlurHome.apk (with Launcherpro), InPocketService.apk, ToggleWidgets.apk (with ExtendedControls), WeatherWidget.apk (with FancyWidget), VSuiteApp.apk etc.

You may be right, I had the Xperia X1 something like 1 year ago.
I had until now FSC T830, HTC Hermes, HTC Diamond, Xperia X1, Samsung i7500 Galaxy (my first Android), Acer Liquid and now the Defy. As far as I remember I always had to charge every night (or every 2 nights at best)
Overall I think Android battery life is worse than Windows mobile was BUT I also have more background programs running now than I had in the WM days.
What I definitely don't like in Android battery life is lack of consistency. One week you get30-40 hours at a charge and suddenly 12 hours... Than you have to make detective work: look what new App might be the guilty one, check what's running in background, reboot and see if it happens again, factory reset, etc. I guess this is the price of freedom

Im on uk 2.2 and i get three days at a push i jus have a weather widget on sync every 3 hours.
Iv also undervolted 300/16 600/29 800/39 with setvsel on performance mode and up threshold on 99% and limit to vsel 1 when screen iz off
Im on three uk so im constonly on 3g and use no wifi etc etc with normal sms usage and a few calls through out off 1 charge

There has to be something wrong in your case. I find that there seems no wifi/2g/3g connection. Could that be the problem?

I dont use 3g ..cuz its expensive in my country ..and I only turn wifi on when I need it
And that shouldnt be the case ...I think id loose a lot more battery if wi-fi would be on all the time

[Q] Investigating a battery drain issue

Hello all,
A few months ago I became a proud owner of a Moto Defy, a great rugged phone that has been working great for me until just last week. For some reason the battery life was cut drastically! So bad that while the screen was off and not touched at all, the battery percentage would go from 100% to 40% in four hours.
what was even worse was when I would connect the charger, the phone would charge completely in less that 1 hour! I didn't seem to matter if I was browsing the web, playing music over the loud speaker, or just leaving it alone, the battery seemed to fall the same.
I began to research online for some answers since I couldn't believe that the battery would just go bad just like that! first I installed a custom recovery that had the option of wiping the battery stats, but that didn't work. then I stumbled across this thread on a battery bug in the android os 2.3.
http://forum.xda-developers.com/showthread.php?t=1039696
Even though the os on this defy is 2.2.1 I thought I was on to something. they talked about an app called watchdog. I also found an app called Battery monitor widget, which allowed me to see the battery usage in milli-amps.
I got concerned when during the day, I noticed a spike in the battery usage that was crazy! the app showed where the usage went from 99ma to 2399ma drain and I lost 8% of the battery in that one minuet! Keep in mind that the battery is only rated at 1500mAh to begin with. With that being said, I was thinking I have a short in the phone! The spike happened again later on that brought my phone to it's knees!
while reading further into the thread, I installed watch dog lite. Immediately after the installation finished, I started getting flagged for an app using over 60% of the cpu while the screen was off! Fancy widget 1.3, I had liked this app so much on my old Moto cliq, I imported it over to my defy.
Maybe I have found the culprit, I donno. This is just my experience so far, if anyone can add to this, please do. I will continue to monitor the phone and the activity of the apps. I am still shocked about the battery drain spikes that I saw! I am still, to my knolage, running the stock rom that came with the defy, now with the addition of Clockwork MOD recovery installed.

i have issues too, in the last week my battery dies in 13-14 hours with normal use. before that, it lasted 24-25 hours with heavy use. i also have sudden pattery percentage drops (which is probably the same as yours, that 8% in one minute). i already tried reflashing sbf/cm7, calibrated battery with cwm and app, nothing seems to work. now i disabled boot oc and use setvsel, and installed battery monitor widget and watchdog lite, maybe those will help :S

Since I installed rc1.5 my battery last for a fairly long time. It droped from 100% to 26% in 23 hours with medium use (data connection always active, when I used it heavily I turned on 3g, I used wifi and I was on a sunny place so the screen was bright)
Sent from my MB525 using xda premium

many have reported battery drain on rc1.5, seems its not present in every case. just installed 110909 nightly, so cant really report on that yet, but ill do as soon as i can.

Im on CM& RC 1.5, my battery last me a long time (more than 30 hours) using a lot of wifi + edge data, and lots of calls and sms, so i guess i dont have the battery drain bug

Battery problems

Hi.
I've been using Mi 6 for 14 months and I recently noticed a huge drop in battery life after updating from MIUI 10 Beta to Stable. Few days ago I changed my ROM to OmniROM because I thought my battery would last long with less Android System battery usage, but in the end it was still the same. My battery used to last a whole day with normal use and occasional game playing, today for example I lost 50% in three hours. On AccuBattery I supposedly have 2400mAh instead of 3350, although the number kept changing for a few days so I'm not really surprised, I don't believe the app is really that accurate.
My question here is if anyone has/had the same problem and what could I try to fix this, except buying a new battery.
Thanks in advance.

I would recommend to completely drain the battery to the point of not being able to turn on even for a few moments, then charge up to 100% for 1-2 times, i had done this to my S5 which had a very crappy battery (it was in use for like 3-4 years with the same battery) and after that it worked like a charm, but, this is a big but, i dont know if this is going to work in this situation.

I'll give it a try, thank you!

Batteries shouldn't be drained to zero.. Doesn't do them well...
But actually I'm having similar problems lately. It drains 10% or more over night in airplane mode.. In on RR OS..

I switched to Lineage OS and the battery does last longer now, I even removed the AccuBattery app. Just in case I ordered another battery and I might even replace it if the battery use turns out to be the same or even worse than before.

Question Overall bad battery life

Anyone experiencing battery drain despite not using the phone intensively? I have mine for two weeks now and the battery life is kind of bad.
I disabled many apps using Universal Android Debloater and it improved, but it's still kinda bad compared to my previous Realme phone(which also had 5000mah battery).
The phone gets warm when I'm using it, so I think it might be the rom that's not well optimised or maybe it is still bloated?

Me too Today.
1 Reboot,
2 Close all apps
3 Uninstall new app.
I hope to solve the problem!
Edit: [Problem solved]

It drops a bit overnight, that is true. But after a working day with 20-30 phonecalls and about an hour of Youtube I still have 60% battery in the evening which is in the top range of any smartphone I owned.

Battery drain can be from just about anything. Any background app including 3rd party ones that go wrong can create major battery drain.
Some people replace devices to try to solve it.
There's a whole bunch of things you can try though and look into. Nothing here may be easy.
My last Samsung would battery drain unless I rebooted 1-3 times every few days. My A53 has zero battery drain problems. Its likely the A54 should be fine too.

It is.
