In smartphones today, we can easily get information on their CPUs/GPUs etc.
But the only thing they mention about the battery is its capacity.
is it possible that some batteries from particular manufacturers would have better charge retaining properties or overall lifetime ?
Is it known whether batteries of say Samsung/HTC/Moto/Asus phones are generally better or worse than others ?
Or it does not matter, and mostly depends on the CPU/GPU and how the software handles the consumption/wakelocks etc ?

I am a bit concerned about the battery life of the upcoming htc. The first reviews I have read about it on german blogs speak from 12 to 15 hours battery life under medium to heavy usage. Even though, one needs to remain cautious with these numbers as the software is not finalized, I wouldn't expect these to double when final.
The Incredible S has a quite satisfying battery life according to users experience. But the Sensation has a bigger screen, higher resolution, a full load of 3D effects and almost the same battery. I fear the battery life will be insufficient in that case, even though dual core is supposed to consume a little less.
Samsung has built a slightly bigger battery on his GSII and people seem to experience a very good battery life. But Amoled doesn't drain the battery when black is displayed and the whole UI has been designed in black for this purpose. So the Sensation will probably not be able to achieve such an autonomy.
Hopefully it will still go through the day under heavy usage. Otherwise I might gonna settle for incredible s instead.
Has anyone read other numbers somewhere?

This is how I see it. Multi-core cpu's theoretically are more power efficient. You spread work over both cores, if software is optimized, to allow for less "strain" on the cpu. From what I can tell they are "optimizing" their Sense UI to run on both cores which efficiently manages the amount of power is being used. This now gives you less power draw hence power is saved. The battery isn't as big as some devices, but in my honest opinion I believe you will get a little more than 12-15 but probably won't get up to double that. This is all based off of my own conclusions after reading several articles. I may be wrong and if you need to correct me feel free. =) All I will say is you probably won't have to worry about battery issues.
I apologize if this is in the wrong section, but this is the best forum I could think to post in. I didn't want to just post it in a device-specific forum.
Basically, I want to know who's to blame for Android's (almost always) poor battery life. It has been several years since android has been out, and it wasn't until a few months ago that phones started having "good" battery life, namely with the Moto Atrix 4G, and the LG Optimus 2X / G2X. and Samsung Galaxy S II
Is the Android OS to blame. Was there something that was going on before 2.2 that was causing this?
My friend's iPhone 4 has a 1420 mAh battery, and it can last nearly two days with medium use, all while receiving push notifications, etc etc..
In comparison, I have to undervolt & underclock my Evo 4G just so it will get through one work day on the 1500mah battery
And it's not just the iPhone. I know people with large-screened Symbian devices that also have great battery life. Even my roommate's HD7 gets much better battery life with similar usage.
I know that usage is a big factor, and the "good" battery life is subjective, but before people drop in and start raving about how android is more "connected", and stuff is always syncing, blah blah blah. I want you to drop your biases, and accept the truth; android battery life has been terrible.
So who's to blame? Google?
I would have to imagine that it's just the nature of the beast in that the iphone and WM7 all have very similar hardware and therefore can optimize there code to suite that specific platform to eek out all the battery that they can.
However the variety in hardware that we all enjoy with android does not enable the same amount of optimizations unfortunately.
That being said, with advances in hardware and software there will inevitably be better battery life around the corner - for all platforms. so i think that the solution would be that manufacturers like samsung, qualcomm, ti and even HTC, Moto to better optimize their products before launch, however out of these i only really see sammy as being able to do this as they are the only one to produce the chips and the phone.
but yeah... just my 2c
Hi people, I searched though quite a few threads and couldn't actually find an exact answer.It also can be a general question for any device.
I have a Micromax A89-good handset for its price only problem is the battery - it wouldn't last much (i'd say 3/4 a day normal use-1450mAh).
My question is what are the subtleties involved in powering such a device with more powerful batteries like a 2600 mAh battery (approx same size). Will it just work fine, giving better battery power to the device. Or whole lot of things come into play? like software and everything or the Soc itself which is made to work within certain range (this one doesn't for your knowledge -same Soc is present on a higher end device a110 with 2100 mAh battery).
Or it may damage or brick your device or may be heating problems occur, there are lots of factors.
So if i can find a similar battery that could fit in - no matter how powerful it is 5000mAh or whatever- do i get approx 3x battery life? or it cant be done?
and making it a more concrete i'd love to get battery suggestions for A89.
Thanks
Hello, recently, we have hear many stories on the news about phones battery's explosion. After doing some researches on the Web and using some common sense and basic knowledge, I know that voltage range and temperature of the battery are strongly related to the overall condition of the battery. Therefore, I just want to ask, generally, for a 3100mAH battery (for Note 2), what is the secure voltage range and what is the secure maximum temperature threshold? Also, what are these factors for the 6500mAH (extended battery for Note 2)? note: I personally don't think that these factors vary with the battery capacity, but I just still want to ask in advance... And I am talking about a lithium-ion battery

I just found the secure voltage range, but I still need the temperature...
So I've ended up using multiple phones that had either the 820 or 821 chipset (S7, 3T, G6), and practically all of them - despite varying battery capabilities and other hardware differences - seemed to have the same general characteristics;
- Middle of the road screen on time. For instance, back when I had a phone with an 801, I could easily get 6-8 hours of SOT using a 3000 mah battery, whereas even the 3T, with a 3400 hour battery could barely reach 6 hours.
- Relatively high or inconsistent battery standby drain. Greenify and Doze seemed needed on practically every 820/821 I used just to keep the standby drain in check.
- Phone often running very hot - especially after extended use.
Now if you're saying those are traits that phones have always had, you're more or less right. I'm not necessarily trying to argue that the 820/821 were steps back for Snapdragons or anything (although I do think the whole need for 2K screens did effect overall efficiency). In any case, my general point is, these flaws - whether they're solely with the 820/821 or longstanding, seem to be corrected with the 835.
Granted, I've only owned one phone with the 835 - the S8+ - and while I haven't noticed any great jump in speed or straight up performance with the 835, I have noticed that practically all of those slightly annoying flaws mentioned above are nowhere to be found.
With a 35000 mAh battery, 8-9 hours of SOT is easily achievable, I've left my phone off the charger overnight to find the battery still at 100%, and my phone hasn't gotten nearly as warm as any of the phones from last year.
In conclusion, in my personal testing and usage, I've found the real benefits of the 835 to be mostly noticeable when it comes to efficiency, rather than performance (which, IMO, is a very good thing), and I suppose I'm kind of surprised that this really hasn't been covered at all by any of the major Android publications I've seen.
You are right, snapdragon 835 is a major improvement, but aren't these initial judgement, 835 hasn't aged till now..lets see how it keeps up with the performance, especially Samsung s8..
