I can (after measuring the mah on both batteries (stock and cheap 3500) using battery monitor widget pro and completing over 10 battery cycles on both that the 3500mah battery is actually only around 2100mah (after about 4 months of use) and the stock is sitting at 1538 right now.... so thats only a bit better than a 30% increase. Perhaps the better name brand brick batteries score better but I haven't tested them...

If you get a cheap 3500mAh battery it's probably just 3 of the stock taped together lol.

All joking aside though, that battery is not going to hold 3500mAh for long, pretty soon you'll probably be holding a lower charge than the stock battery.

I've used T15; the life was worse.

There is a simpler explanation to our battery life being shorter that isn't a fault in our hardward/software: the way we use our phones drain our batteries faster. I do realize being wrong on the internet is something everyone tries to avoid at all costs, but maybe you can admit that it is possible we use our phones more than you? Or rather than our set-up being bad, yours is just good?

In attempt to end this here before this turns into a "I use my phone more than you" pissing contest, all I'm going to say is I've used many ROMs and kernel combinations, and there hasn't been much variance in the battery life. Data always drains a lot; having the phone in a low signal area drains surprisingly quickly; calls/games/bluetooth/movies drain a medium amount.

As for the 3500mAh batteries being bad, yeah, you're probably right there. I don't have experience with extended batteries (I've actually just received a 3500mAh today; I'm skeptical about it, so I'm testing it the first chance I get). All I know is I've read reviews where people claim the battery lasts much longer. My message was based on the assumption that the battery is the capacity that it claims to be.

Oh and since Battery Monitor Widget has been mentioned, I've been wondering about the accuracy of that app. I've heard people say the only way to get true readings is to test the battery independent of the phone with special tools, etc. I've also heard people say that it's accurate. So I just want some of your opinions on BMW if it's not too much to ask.

I thought I may be wrong, so I tested it.

T15 running at stock 1GHz with some crafty UV and I just got the yellow battery indicator at 20 hours of use, and pretty heavy use too.

If the dumb XDA app would upload my screenshots correctly I could show you right now but I'm going to have to wait until the phone dies so I can charge it so dropbox will upload.

About BMW, it's an estimate, but after a few charge/discharge cycles the estimate should be a pretty accurate one.

Hmm, okay. I didn't really find interest in the whole BMW thing until a few days ago when it finally gave me an estimate of my stock battery capacity: 1623mAh +/-22%. The 1623mAh surprised me, but the +/-22% kind of explained that high result to me. Since that pretty much means it's somewhere between 1266mAh and 1980mAh (unless I misunderstood the +/-).

Also you're still ignoring my whole "we may use our phone differently than you" hypothesis. I can assure you that when I switched to T15, my battery went down faster. That's really the only objective thing I can say. Everything else boils down to how I use my phone which, as I mentioned before, is highly subjective.

I dedicated one weekend to draining my batteries to see how long they'd last and both of them died after almost exactly 4h. My process was draining it normally, charging it to 100%, charging it for another 20min, unplugging it, turning the screen to 100%, disabling screen time-out, setting processor min/max to 1000MHz/1000MHz, and then recording how long it took to reach 0%. Although I agree that the conditions were unrealistic, this is still far more informative than any "I use my phone heavily and it lasts me like 20h"; if you can do this with your phone and have a result that's different than mine, then I'll definitely look into my setup further. However, as of yet, I only have your claim that it lasts you longer on what you consider "heavy usage".

Believe me, I'd like you to be right and find out some magic settings on my phone that make my battery last longer, but the best and simplest explanation so far is I just use my phone differently than you and that results in faster battery drain.

EDIT: if you still disagree, have a better way to test how long my battery lasts, or have that screenshot with my battery drain method, just PM me it or something. Although I'm interested in what you have to say and have no problem with discussing this here, we're pretty much hijacking this thread to discuss my stock battery haha. If my battery was an extended battery which is the same size as stock, maybe it'd have some relevance, but yeah... it's not.

I agree with what your saying but what I have here is just a normal day of my use.

Not trying to argue or anything

Wow, I wouldn't be interested at all in extended batteries if mine lasted that long.

I generally use data instead of wifi, and data eats battery waaay more than wifi. So that could explain some of it.

Also you kind of saved me today when I couldn't figure out why the new extended battery kept freezing my phone. Then I remembered what you said about the lower voltages potentially causing problems and flashed T15 instead of ELP; the extended works perfectly fine now. Sooo... thanks for the indirect help haha.

Lol

One thing I noticed saves a lot of battery is going into dialer and typing in *#*#4636#*#* and it will bring up a menu.

Tap "Phone information" and go down to where it says "Set preffered network type" and set it to GSM auto. Reboot.

This makes it so when you have bad 4G reception it drops to Edge, when by default the phone just works harder to keep the 4G which really eats battery.

I don't see why it's not better to get a external battery pack instead though.

Adding extra bulk to your phone is better than carrying a second phone-sized device in my opinion. Also the benefit of having the charge already in your battery instead of needing to recharge to make use of the extra juice.

I guess if you carry a bag or something, then the battery pack can just be kept there. That way it's not taking up a pocket and you get to keep your slim phone.

However, I don't see a workaround to having to charge it once the battery is low. That's always going to be an inconvenience.

So in a nutshell: I see the benefits of an external battery pack, but it just adds a lot more inconvenience.
