[DISCUSSION] GSM Chip Is The Problem For Battery Drain? - Sony Ericsson XPERIA X10 Mini

Hi Brothers and Sisters,
I am opening this thread because i need some clarification on why we have so much battery drain on our x10 mini pros.
I have x10 mini pro, using nAa's kernel and rom (latest). I have seen lots of things in this phone and OS and they are working very good. but we all have battery issues and mine goes out soon as i start talking. it's like every 2 minutes or so the battery loses 1% of its juice. and using internet like edge network, or to make it even worse, hsdpa kills it instantly.
I ever thought that SE made the wrong choice of using its gsm communication chips for phones like these. because i see samsung and other rivals compete and they have good battery life even after a 1 or 2 hour talk.
And yes i know it all depends on the network coverage and how much signal strength is available, but the xperia series itself (old 2010 models) are much bad in this case. after i have a one hour of talking nearly 40-50% of charge is gone down. nothing like that happens if i listen to music loudly or play games or even read something. But using internet and calls make the big hit.
Resetting the battery stats doesnt make any sense. i have used at least all the roms here in the forum and i wonder, it ain't the rom's fault, it is the communication chip (i.e the gsm/radio chip) that is on board. That consumes the battery madly.
The matter continues on the newer series too. and they (even the mini and mini pro 2011 versions) have 4 hours talktime. what is going on?
Is SE using any flawed chips that are wasted somewhere?
Has anyone thought about this on what i am talking about? My phone is just one year old now. and everything is fine. except for this battery drain.
Has anyone have any thoughts about this matter? Please share it here if you like
This is just an open discussion, not a question and answer.

Will battery life ever get better?

3 days in w/ my TBolt and VZW announces the Incredible 2 yesterday, releasing at the end of the month ...
Rumor has it that battery life will be much better than the TBolt, so is anyone returning their phone right now due to battery life or will there be an improvement once new ROMs are released? Is it worth the wait?
maybe it probably will never get any better. i would seriously maybe probably consider thinking about debating on planning on returning your phone.
i dont know what htc/verizon was thinking when they released this. i mean technology like this and i have to charge every day!! unbelievable!
i probably think inc 2 will maybe be better since its a 3g phone.

I like the TBolt... And not waiting on a rumor for the Dinc 2
Last I checked, the Dinc2 is a 3G-only device.
I haven't had any trouble with my Thunderbolt's battery life easily getting through a 8hr work day with plenty left over.
I'd say it's an almost certainty. There seems to be a problem/bug with the radio which makes it drain a lot of power in certain areas (my house seems relatively fine, but in town it's not ... maybe certain towers for some reason? No 4g in my area, so that's not it) when you have mobile data enabled. I'm currently at 78% battery with 13h 30m on the clock ... by turning off mobile data in the areas I've discovered where it decides to draw the obscene ~900mA (or some other fairly constant, very high number) when I encounter the "bug", I've managed to essentially make the battery life as long as anyone could expect.
For some reason, the radio will not admit to drawing practically 90% of your battery in the battery use menu.
So, I'm thinking future radio software/firmware updates can drastically improve battery life if they discover the cause.
Currently, without the area with the bug (I'm at my house) and screen off, I'm drawing 42-60mA on 3g radio and 40mA wifi. And areas with the bug, it's 700mA minimum with spikes often at 900mA and above.
Seriously, how long would you expect a laptop battery to last? These new smartphone are basically mini laptops. I'd be lucky to get 4 hours out of my laptop. My phone will make through the day with moderate use.
Just my 2 cents

Same here..
Bought a spare stock battery on launch day expecting the worst, but have yet to have to use it. I make it through the day with good use no problem. Today was even better after loading das BAMF 1.3 ROM w/ kernel, overclocked to 1.2GHz as well..
Mine has gotten better over time. Im sure with the next couple updates the battery life will get better. But if you dont care about lte or the bigger screen you might just want to get the incredible 2.
My battery has gotten better over the past week. It's tolerable now. It will make it through a day, which is all I really need.
It's never going to get good battery life though.. there's a lot of stuff packed into this phone and on top of that, the 1400 mah battery is already small for a device like this.

Last night I unplugged my phone at 430am. Went back to sleep woke up about 730 and battery was at 45% with WIFI on. Don't know what's going on. Some nights 8 hours with 4G on my phone won't even burn 10%. The WIFI thing is puzzling to me.
Can't say for certain, but I've heard gingerbread significantly improves battery life in most phones...
and rumour is, we will get gingerbread official in Q2. (unofficial via cm7 maybe sooner???)

[Q] Screen on battery life

Just curious as to what other folks are getting for actual screen on battery time, as in, what do you think you would get in constant screen on usage?
I don't suffer from really bad battery drain, I think I could get a couple of days of light use from it.... but it does fair chomp the battery in use.
I reckon I could completely drain the battery in 3 - 4 hours of constant use of say web browsing, the odd game, texting etc, and am just wondering how that measures up with others; with talk of this device having iphone 4 levels of battery life, my last daily driver was said iphone, and that device managed about 50% longer screen on time, so it doesn't quite match that, but some are saying theirs is better?
I don't have the brightness cranked or anything, and I'm not exactly unhappy, but it probably matches my Incredible S for battery life, and both phones are perhaps slightly better than the Nexus One or Desire, which I didn't think were amazing in that department...

I also got about 3-4 hours with brightness set to 20%. I originally wonder if it's my problem only, as most of you say the battery can easily last for more than 1 day.
In my case, most of the battery is used by the display, given I used each about 1.5 hour before and after work during travel (with display turned on). So 3 hours of display on + some phone call and sms, that will drain the whole battery for me within one day. I think I need to buy a 2nd battery when it is available in Hong Kong.

Yeah same here. Display takes almost 50%. I have automatic brightness set on. I could of course set it to minimum brightness and it would decrese the battery consumption but I think it is ridiculous that I first buy a phone which is praised for its bright display and then I turn it to the darkest. Completely stupid. I tried that quickly and even my old Desire looked better then.

To shorthand it for everyone, the SGS2 came in fourth out of four when using web scripts until the battery dies utilizing the stock browser. Results are:
Web browsing battery life test:
Apple iPhone 4 – 7:40 h
Sony Ericsson Xperia Arc – 5:25 h
Samsung I9100 Galaxy S II – 4:59 h (Opera Mobile browser)
LG Optimus Black – 4:30 h
Samsung I9100 Galaxy S II – 4:22 h (stock browser)
Samsung I9000 Galaxy S – 4:06 h
So since the SGS sucked more, I guess it's the Amoled screen doing them in. They should have used black web pages and the SGS2 would have won.
Actually, if you think about it, the SGS2 is pushing more pixels and has a dual-core processor with hardware acceleration to feed. So at least beating the SGS shows some progress.
Thanks for the comments guys. Good to know it's not just me. It'd be nice to get the same as the arc... So maybe there is room for improvement, but all those who say it can match the iphone are living in dreamland! Saying that, I'll still take the bigger screen, ta! However, certainly reviews like techradars are a little misleading imo.

It'll be interesting to see how the iPhone 5 performs with a bigger screen and dual core processors. At least we don't have to send our phones back to the mother ship to get the batteries replaced when they discharge for $150. Come to think of it, with a pocket full of extra batteries, we'd be able to go 24/7 with a couple of pit stops.

Luckily, the battery is so light that possibly having 1-2 extra batteries won't feel any weight inside the bag. If Samsung can release a "battery" direct charger (instead of charging through the phone itself), it will probably make my life easier.
Anyway, though the battery life is not as good as I originally expect, I still consider this phone as my best phone, EVER.

not really, the SGS2 has less pixels than the iphone 4 in that test, for example. and the iphone 4 also is hardware accelerated for browser and all UI elements, so its kinda a close match. smaller screen, but more pixels, but SGS2 has larger battery and AMOLED, so really its matched up.
Galaxy S2 Battery RESPONSE
Hey Guys,
I sold my iphone 4 to purchase the galaxy s2, never owned an Android phone before, I posted a post on the forum about rooting methods for the S2. Before I purchased the phone i did research on batter life and I read most users could do a full day or close to 2 days without charged. They said it had a better battery than the iphone 4 this was the decisive factor which lead me to buy the phone. To come to this post and read that the pone battery last only 4 hours for browsing this is childs play. I feel somewhat cheated and deceived.
Has anyone in the forum here achieved the 24 hour battery best while using the phone in full capacity ? How is this acceptable to you guys, 4 hours ? This is unacceptable.
Thanks

Yes, I too read of the great battery life of this phone - but not on here - but on reviews from the likes of techradar etc. Very deceiving. That said, I can get through a typical day quite easily on a charge, but it's never going to take on the iphone on battery life no matter what they say.
That said, I think (hope) the situation will improve with more mature firmware.
It is a shame, but for me, its not a dealbreaker, especially as I am always near a power source.

most iPhones do not truly multitask, so they do not waste power. it is also a walled garden, with fewer freedoms, and fewer possibilities to mess up admittedly highly tuned and optimized power management scheme. Remember it is one OS on one piece of hardware, with every component tested and tuned to near-perfection.
and yes, if you set your SGS2 browser at 100% brightness, auto-enable Flash (that will waste power on all those moving ads etc that you are not even looking at), turn on music in the background streaming it to your Bluetooth headphones, enable Gmail sync, Exchange sync, Facebook, GVoice, GTalk, Yahoo Mail, Yahoo Chat, AIM, Twitter, etc, and browse (read mostly black text on mostly white backgrounds) for 2-4 hours, your battery will drain.

Hello,
Can you or have you used the sgs2 for 24 hours or more of heavy useage? Can you provide testimony for those who feel limited to the 4 hours of browsing others experience. In respect to your prior post, using your sgs2 surfing with flash OFF, twitter OFF, exchange sync, OFF,Google Voice OFF, BlueTooth OFF, Can you get a full 24 hours usage out of the phone ?

I think the difference may be in scrolling. It doesn't sound like the test included scrolling of web pages - just loading. And I suspect that the super smooth scrolling you get on the SII gives those dual cores a good workout.

[Q] [polemic question]

Thanks to all developers for all The hard work to this comunity.
i think we all lile to come here and see a New Rom.
But in The end what is The diference from all of The roms here ?
No bugs or less bugs ?
More colours or less colours ?
I just want a stable rom with 24 hours of battery...but battery that let me use the SG2,,,use push mail , use GPS with acuracy , surf in The web ....
The iOS 4 let me do this...
I tried almost of The roms here...cant get more than 12 hours...diferent kernels...
I dont want set CPU , juice defender etc,,,i want a device that i dont want to think if i surf On The web ...i dont have battery for tonight.
I think The developers do a lota of effort..i think The sg2 is not good enough...
I bought 3 batterys ... All The same , waiting for The 2000mhn from Samsung ...last hope ...or i Will be back to iPhone .
Any advice On a good cobination / rom and kernel ?
Btw : The quality of The housing of The sg2 is poor..
Thanks for you advices , and thnks to all developers .

My SGS2 has better battery life than my iPhone. The only bad thing about the casing is the battery cover...that's the trade-off of having a removable battery. Sounds like you're using your battery wrong.

Galinha, there must be something wrong with your setup. On an iPhone 4 I was getting 7-8 hours of battery life. SGS2 lasts me a day at least. I'm using stock ROM and kernel.

Lol it was just a joke (remember iPhone-you're holding it wrong?).
I'm using cognition and ninphetamine. I took my phone off charge about 15 hours ago and my battery is at 73%. Made a few phone calls, sent a few messages, played wordfeud, used opera and some random stuff playing around in the phone. I suspect there might be something wrong with your phone or there's an app that isn't running correctly. Why don't you back up your photos etc and try a reset?
Definitely something is not right because for me the GS2 has the best battery life out of all the smartphones I've used!

Mate my phone is the best for me. i was like you wondering what im doing wrong and i got **** battery. but i read about it and chopped and changed kernels till i found the best one for me. now i can use my phone for a day or two without charging it
I am coming from an SGS and have just snapped up an SGS2, both of which I am very happy with. I am a heavy smartphone user, I can't do without them because they have made my life easier and more enjoyable in a number of ways.
There often are occasions when I would never make a full day on a single charge, on *any* smartphone. Now, one of the iPhones' several showstoppers for which I could NEVER buy one and for which I think it's an absolute POS and it's really for people who do not need smartphones, is their non-removable battery! The SGS2 has a removable one so I can't understand all the talk about having to worry and limiting oneself in using one's smartphone!!
An original Samsung battery for the SGS and SGS2 costs around € 18 here in Italy and an original desktop charger is about € 20. I had 3 1500mah batteries for the SGS and have 4 1650 ones for the SGS2. However long I am out and about I NEVER run out of juice and however many batteries I use in any given day I just charge them once I am at home! What's easier and simpler than that????
Even when I have just used a single battery and still have some charge left by the end of the day I NEVER plug in my phone at night, I put it in airplane mode and keep it handy on the nightstand to use as an alarmclock and to quickly check whatever I may need after I go to bed (an appointment, a note, something on the net etc etc). Once the battery runs out (during the next morning or whenever) I switch batteries and charge the depleted one when I am back home. So even if you can make a whole day on a single charge having at least 2 batteries and a desktop charger which can charge your battery alone, you would never have to keep your phone on the leash of the powercord and limiting your freedom in using it!

[Q] iPhone 4S vs. Samsung Galaxy SII

Hello all,
I'm currently a Samsung galaxy s2 user, just switched from using the iphone 4 because of all the rumors about the galaxy s2. And till now im impressed by everything it has to offer except its battery life.
I love my galaxy s2, but the only problem is battery life, and thats the main reason im being pulled over to buy the iphone 4s!!..
getting that isnt the problem..
I tried way too many custom ROMS, different kernels etc, but ended up with an average 6-7 hr battery life with heavy usage and that doesnt even involve listening to music while commuting. If i did that as well, im sure my battery wud barely last 5 hrs... which isnt ideal at all, im sure everyone feels the same way... Right now im on stock KI3 firmware, rooted. KI3 is slightly better than what bell gave me as stock - KG2.
now i want some strong points of why i shouldn't move back. I've been an iphone user since the 2g iphone and it was amazing!
Only if i could improve my battery life on galaxy s2 i wouldnt have these temptations to move to iphone again.
Should I move back to the iPhone?
no, galaxy s2 is the best !xD
my battery is very good so i don't care just try some kernels or roms
iPhone 4s is much better than SGS2 IMO.
Better size, better display (imo SAMOLED+'s colours are too cartoony), better resolution, better camera, better audio, much better battery and a much faster processor.
Also, iOS has proper dual core optimizations and actually makes good use of the A5 chip, wheras with SGS2, you'll have to wait for a stable ICS rom comes out.
Despite the negativity of the i4s, I personally think it'll be one of the most underrated phones this year.
But that's just my opinion.
My s2 often gives me 16+ hrs of heavy usage (my phone is from the first batch) my other half got a white s2 a few weeks ago and he has dreadful battery life. Both same firmware ect. Although mine is made in korea both battery and handset. His is made in china. Different colour mainboards too. Mines blue his is green.
Sent from my GT-I9100 using XDA App
Well just to make the point clear, you will never get your sgs 2 to have as much of a battery life as the IP4S. iOS is simply much better at handling battery life than android.
Now it depends on what you want really. Do you value battery life over functionality/choice?
Personally what do you expect of a phone with a dual core 1.2ghz processor? If you expect 12 hrs now that is simply idiocy. You have a laptop that can do that? I don't cuz mine lasts 2 hrs with heavy usage. I haven't read of any laptop being able to last 12 hrs of heavy usage either. No I don't expect a laptop to have a battery life like that either. Now this is a phone with a processor better than most if not all netbooks, it is not going to have a 8hr+ battery life with heavy usage just like a laptop.
I feel your pain with battery life. Also, screen burn in isshowing its face on mine too. But threw iphone is waaaaaay too locked down to make it an easy choice.
Sounds like you dont have things set up correctly to me or your using some resource hogging apps.
Im on wifi all day, send between 40-70 sms a day, couple of phone calls, tweetdeck auto updating, around 20mins of music (well, podcast, but it is an audio file), auto updating of all my apps enabled in the market and the obvious hour or so web browsing and 10mins or so of minecraft when I sneak off for a break in the toilets and I get home with around 30%
Dont forget, your also comparing a closed up OS which has been around for a fair old while to an open one which is still reasonably new which each phone manufacturer has his way with before chucking the phones out
Im not going to fight the android corner as you admitted yourself you are 'looking for reasons to not move back'. Which sounds as though you have already made up your mind.
If you want to go get a shiny fragile phone with a half eaten apple on it by all means do Glad you've at least tried Android though, your light years ahead of 90% of Iphone owners who live around here lol.
must be something thats killing your battery in the background. I quite easily get over a day and between 5-6 hours screen on time. Longest ive had was 6hr 38 mins screen on.
Download better battery stats and see whats running in the background.
Lawl you all are missing a very important statement in his post. "HEAVY USAGE"
What is heavy usage? Web browsing, playing a 3d game, watching a video, recording a video, taking pictures, etc. So of course he is going to get 6-7hrs of battery life.
I agree with the above post. find out whats draining your battery. Shouldn't be that low...unless you are just sitting on your sofa browsing constantly because your so excited about a new phone like i was.
Also you can buy a dock charger and extra batteries set for cheap together (ankhers set) so you never have to plug your phone into a charger again
But it sounds like you have alot of money to burn...then why not...being in a locked system isnt so bad when your willing to just buy every app and media at premium prices and your happy with the interface
Thanks for the quick reply guys, and yes, i m loving my galaxy s2 as i mentioned earlier. And yes, im a heavy user, around 100 texts, playing 3d games (sandstorm, brothers in arms etc). I barely keep wifi on as i haf 6gb of data which is almost unlimited. and im getting 7 hrs, which apparently seems to be good. If thats the case then I have nothing to complain about...
And in terms of money, lol i dont have any... its just i could get an iphone if i sold this one... no way i could afford to keep both!
Stick to the SGS2 and wait for the SGS3 till then.
Hmm, If were I, I would like the iPhone 4S. The iOS 5's new feature iCloud and iMessenge really attracted me.
And can get many apps for it:

SGS2! iPhone4S is inferior in many many ways. It's a ****ty phone.

u should wait untill the ICS rom is out. that should improve the battery life, because it will be customized to a dual core processor.
Iphone 4S is quite a good phone, but I'm personally against Apple's politics regarding software and price. I don't want Itunes, no format support like FLAC or MKV, no Flash. Also Android has more customization abilities in themes and menues.
I like the big screen and weight on the GS2. Well, the battery life could be better on SGS 2. But there's a Samsung 2000mah battery available at the moment and you can easily replace the battery.
I have been in the same boat in fact I have swapped my Iphone 4 for a SGS2 three times, until finally I realise that the SGS2 really is a SuperPhone.
The reason you will find battery life not quite as good as the Iphone4, is basically down to the fact the Iphone is not actually doing a lot.
I waited until iOs5 before swapping back to this truly, greatest phone since the HD2, iOs5 really is a disappointment to say the least, you get a pull down bar that kinda copies Android to a point, but fails in the fact with its Iphone basic-ness yet again, the weather links to the most basic of weather apps, the notification animations appear at the top all very nicely, but the top bar doesn't state that notifications are listed within, they tried to match the Androids version but in true Iphone style, didn't leave in the design to allow users to feel its their notifications.
One thing you will never get away from even jailbroken is the fact you are not free to choose...you will never own your Iphone, it owns you, Android on the other hand is the opposite and with the SGS2, its power and freedom is far more adaptable than the iphone4.

[Q] Need to check if this is normal?

Hi SGS2 owners and experts. Im new here and a proud new Galaxy s 2 owner now. Im quite android savvy coming from the Spica development from Samdroid. I'v got a brand new GS2 on contract and wondering if the things I'v been experiencing are normal.
Battery life is only 14 hours with light usage and 3g, GPS and bluetooth turned off.
Phone gets warm around the camera sometimes, watching video and browsing the web.
Battery gets warm while charging.
Wifi reception is horrible.
Front facing camera is laggy.
Thats all I would like to know if its normal or should I take my phone back for new one.
Its running on Samsung firmware, gingerbread 2.3.4 XXKI1

For battery life im getting the same and im on checkrom and tried alots of ics rom im the same as u for battery life
And my device is the same the top left of the screen gets worm when multi tasking when the weather was cold i didnt feel it
But now after its summer i can feel my device getting worm abd hot when playing hd games
For battary mmm it gets little worm when charging
But if u use ur device while charging it will get hot ofc
Update to 2.3.7 or 2.3.6 the wifi will get better
Front facing camera yes its laggy
My advice update ur firmware or use custom kernel it will make ur battary and heat little bit better

yup all is normal an giv the phone some time to settle like charge and dischsrge cycle...and flash diff kernel an c which suits u.
Ya it's a bit weird to see people still on GB and not on ICS, but for sure update to latest update on GB (or try ICS).
As ayhamx360 said - try a good custom ROM. Look for one that has a lot of users and help. Check what bugs there are and anything else that's important to you (like battery life, heat, camera, wifi, etc).
PS
Most smart phones only last a day and need charging daily... it's the nature of their screens and other hardware excelerations. Newer phones will be coming with better tech that hopefully can consume less energy.
*That being said, with the right tweaks and kernels it can lost longer - mine is usually good for 1 day and 8-14hrs (1.5 days).
Your battery life seems low, but you may need a couple of cycles to get a more realistic idea.
Never had any of the other problems you mention.
I'd try XXLA4 - either stock or as part of a custom ROM. It's very stable.
Thanks for the advice. I sure feel better now. Thought I had a dud phone. Yeah I'm waiting to update ICS via Kies but old sammy hasn't released the update in South Africa yet. My phone is a little new to me to start messing around with custom ROMs like I did with my Spica. I'l prob switch to Cyanogen 9 when its stable.

I remember having much of this when I first got my S2, poor battery life, phone gets hot around camera (the cpus are located behind it) warm whilst charging and although wifi reception was never an issue, it would drop the connection if left idle for short periods of time, (sleep policy was set to off), most these will subside once you've updated to the latest firmware version, especially the heating up, and battery life will improve once the battery has been properly cycled.
