Seidio/Mugen/Mobi? Which Extended Battery for Tilt/Kaiser?

Hi-
I apologize if this has already been asked. I *DID* search around this site, several others and even Google but no one seems to have posted a comparison of extended battery compatibility along with pros/cons of the expanded battery cover backing...
So, like everyone else, my Tilt doesn't last overnight w/o a recharge. In looking at my options for extended batteries, it looks like the largest are the Mugen 3000, the Seidio 3200 and the Mobi 3000.
I'm curious as to peoples opinions on these major points:
1-Duration coupled with whether the battery causes lock-ups/freezes or other errors for the phone...
2-How the revised back cover of the phone compares to the OEM cover with respect to the camera lens, speaker and GPS.
3-Cases and cradle chargers that will work w/ extended battery covers...
4-Tweaks or other hacks needed for the Tilt to recognize the extended battery time.
Thanks everyone in advance!!

Instead of other I think you should have put the option of " I dont know". I think people clicked for the sake of clicking to see the results quicker. My 2 cents.

extended battery
I have a Boxwave 2700 mah and a Seidio 1600 mah battery. The boxwave is from Taiwan with a humped back cover, so I can use my Seido holster, but will not fit in my cradle. Does fit into my Brodit car holder though, and the full backed extended battery cover will as well.
I cannot for the life of me get the correct battery reserve power reading correct. I have tried every tweak and twitch I have read and perused the registry for settings not mentioned elseware, as well as various 3rd party battery utilities, to no avail. Quite frustrating, as I can alarm on low battery, pull it out, put it back in and have 45-60% battery left on the meter. Don't know what else to do, as it does it with my 1600 and 2700 and did it with a "borrowed' Mugen 3000 for a test. Tried all the reccomendations of running it fully down and doing recharge, all that stuff, still wrong indicaitons of remaining power.
This is my greatest frustration right now with the Tilt I have and the other 8 I have bought for employees.
MWS

wow! im having the same problem!
got the mugen 3000 and the reading is always off!
I cant find any solutions!

I ordered the Seidio 3200 battery and tried charging it in my AT&T 8925 Tilt. I left it on charge until the light turn Green.
Starting using it and within 8 hours I was at LOW battery and system died. I removed the battery and put it back in and the battery indicated goes up to 73%.
What is the deal here. Is it my phone that does not understand that it has a larger battery or is it the battery. Since that time I have sent the battery and got a new one and the same thing.
Is there some software utility to tell the Pocket PC that it has a larger battery.
Confused....????...!!!!

Wow, so...
As I sit here perusing options for replacement Wizard and Kaiser batteries (my sister's phone and my own...) I suddenly fear the pointlessness of choosing an extended battery! Has any headway been made on these extended battery glitches in general?

Nope. The Tilt's hardware always expects the standard battery's capacity, and will turn off when that is reached even if the battery is actually twice the capacity and is still half full.

So what you're saying is buying an extended battery is useless because it will shut off at the regular Tilt battery level? Well, glad I read this thread, I won't waste my money.

Yep. However you can remove/reinsert the battery and have more running time again. But then in that case as you have to turn the device off and open the case anyway you're better off getting a 2nd standard battery and swapping it when it's empty. Saves you from having a Kaiser that's twice as thick for nothing.

What About....
Well, I think one objective would be to try charging it as often as possible. It may be that if you plug it back into a charger, it will grant an extension of time. But in the event you are unable to charge it, you could simply remove and reinsert the battery to continue on. Has anyone tried this? I'm curious to know.

"So what you're saying is buying an extended battery is useless because it will shut off at the regular Tilt battery level? "
Could someone please clarify this as I find it confusing as well, I'm just using the times and percent for reference to understand.
Lets say with the stock battery it takes 8 hours to get to 40%.
Will an extended battery like those listed give me longer, like maybe 10-12 hours before it gets to 40%?
I too have searched and read everything from people swearing to get no extra time at all no matter what they do, to people getting double the talk/data time and everything in between, including but not limited to that the usable time gets longer with each recharge. If I'm going to have to take the battery out 3 times a day, I might as well just get 4 or 5 extra stock sized batteries for the same price.
Looking for someone to clear the fog...
Thanks in advance.

Take a read from my post on here http://forum.xda-developers.com/showthread.php?t=336896&page=2
Battery 2700mAh:
"Full discharge removed battery and replaced and gained 10% so not that much of a difference no where near 50%
So effectively i have 2435mAh battery & 10% reserve so still far better than a 1350mAh."

I wish aztilt would have posted which battery he/she has.
aztilt said:
I am one of those that is very happy with the extended battery because the duration from turn on to auto shut off by the phone is at least 3 hours longer than the OEM battery for my usage. I don't have to think about charging the battery or swapping the battery until I get home at night from work. And there is still the option of remove and reinstall the battery if I don't want to charge it right away. I rarely if never need to do the latter.

If I could get 3 more hours before shut-down, that might be worth it. It would mean 90% of the time, I'd get 12 hours of use as long as I didn't need the GPS. It would have meant last week I would have not spent an extra 30 minutes on ice because the GPS quit with less than a mile to go, but I didn't know which way, and I had not way to charge it, so I spent an extra 45 minutes trying to find the highway home when it was time to leave. Just 3 extra hours would have been perfect.
I can't tell you how many times an extra 30 minutes even would have made all the difference in the world, and I really can't think of a time when I needed more than a couple hours.
I realize I'm playing to its weakness. I rarely use the phone itself, but I'm always in email, rss feeds, web browsing, listening to music and using the GPS.
If an extended battery will get me through a normal workday without having to rush home to charge it... That would make me a happy camper.

I have the Mugen 3000

I have the seidio 3200 and after i fully charged it for the first time use, I use it for like 12 hours of txt, calls, internet and normally at the end of the 12 hours i have about 20% of battery left. Just mainly depends on what ROM your using, what radio your using and what programs you have running. Just because 5 people have the same battery doesnt mean all 5 people use their phones for the same thing. Best thing i found is find the one with the highest battery life and go with it.

hd2 battery is killing me literally!!

i spoke to htc about the abysmal battery life, they say that there could be extended batteries in the near future, with a new back cover (with the back sticking out)
i dont mind charging it every day but
everytime i do something basic, for couple of minutes, it goes down by 1 percent, everything is turned off, gsm 2g mode, etc.
anyway the guy at htc said its due to the massive screen, this is what drains majority of the juice,

For what this device has and what it can do the battery life is pretty good, if you just use it for a few random pics, bit of browsing, bit of music and a few calls you should get a days use, if you sit there for ages messing with it its gonna drain.
Im pleased with it myself, apart from the bugs, but waiting......

It's killing you literally? Step away man!

I find the battery life on-par with other smart phones I've owned. I use a desktop cradle (well should soon be using a desktop cradle) and an active holder in the car, so I find the battery keeps up OK with a typical day's use for me. The biggest battery killer is when the screen is on full brightness so I find essential to have the phone on power when I'm using the satnav.

I had really high hopes for this thread when I read the title. Needless to say, I'm pretty disappointed.
Where's the death I was promised?

Die and prove it.

To be fair most smartphones drain their batteries pretty damned quickly. Disconnect your data connection when you're not using it and bluetooth too. OK so you won't get weather updates but you'll save battery life. Just charge it nightly and buy a car charger if you really drain that sucker!

Wow, I think battery life is good considering the screen, better than I expected.
Currently, with screen set to 70% brightness, push email on 0800-1800 with hourly retrieval outside those hours, hourly weather/Twitter update, automatic Quick-GPS almanac data update, I last all day (~0700 to 2300), and still with about 20-30% headroom with the following use:
Push email as per above settings
50 minutes GPS tracking
50 minutes bluetooth on (heart rate monitor)
1-2 hours listening to music
Around 1-2 hours high-drain use (screen on, using cellular data/WiFi/GPS - for example browsing/app use/gaming/watching video)
30-40 SMS
15 minutes calls

One simple little trick that I learnt some time ago to preserve battery life is ..........turn down the brightness of the screen display. The brighter it is the more juice gets used.
Get the screen to turn itself off after, say, 30 secs of use. That also helps.
The rest, such as killing off data connections when not in use, etc, you already know.
It never ceases to surprise me at the number of negative comments re battery life. The impression I am left with is that if the battery does not last at least 2 months between charges, even though it is being hammered to within an inch of it's life, then that makes the battery performance rubbish. Anyone ever heard of a battery charger?
It's a really easy to use piece of kit that comes with your device that can be plugged in at night when you are asleep, leaving your device fresh for the morning.
Amazing.

What the heck do you expect from such a phone? The energy management is kinda good and it's the display that kills battery life. You have to get use to it. At least my Touch HD seems to last much longer, but I would never change back.
If you watch a video your battery capacity drops quickly. I estimated 4,3-4,5h of HW-acc WVGA video and 3,5h with a non-HW-acc VGA video. Not that much but it really looks fantastic.
My Solution for this problem is: second battery, extended battery and/or load the battery whereever u can. My normal usage drains 30% of the battery a day, so I get 3 days of normal usage (I'm not an excessive handy user). The standby duration is with 300h not that good, but yeah that means still 12,5 days of standby if I calculated correctly.
The point is, that the phone is that good that I'm attracted to play with it and then the battery life tends to last just a day or less.
I bought a second battery (~22€) just for longer rides. I think it's ok.

EEK!, don't come on this forum and complain about the HD2! not allowed. this is now the official HD2 Appreciation society, don't ya know.
I recommend instead you buy some lube oil, massage it into the device, light some candles, play a bit of Barry White, and all will be well.
Then come on this site and reassure all the sensitive souls here that it is indeed the Holy Grail of mobiles and admit you are a Troll for finding a fault with it, and daring to ask about why it does not preform as it says on the tin.
And final advice...In the words of legendary Basil Fawlty... Don't mention the War !..or in this case, the Keyboard!!, I mentioned it once...and thought I got away with it..but no.

Exactly !!
1000 Mhz this bugger does.
And really its more then just a phone. with the battery cunsumption like wise.
But they told me one thing,,. something that Noone does
When you get the HD2. Its battery got 20% juice init.
Thats not for fun of the company (prolly sanyo) was laizy and dint bother to fill em 100%.
You have to charge the battery 6 to 12 hours and to peeking at your new jewel.
And i know Noone ever does that. But it ensures batterylife and eficiency
Here is the article >>
Initialize a new battery. New batteries should be fully charged before their first use to obtain maximum capacity.
Nickel-based batteries should be charged for 16 hours initially and run through 2-4 full charge/full discharge cycles, while lithium ion batteries should be charged for about 5-6 hours.
Ignore the phone telling you that the battery is full--this is normal but is not accurate if the battery is not initialized.
#DO NOT fully discharge a lithium-ion battery!
Unlike Ni-Cd batteries, lithium-ion batteries' life is shortened every time you fully discharge them.
Instead, charge them when the battery meter shows one bar left.
Lithium-ion batteries, like most rechargeable batteries have a set amount of chargers in them.[1]
2Keep the battery cool.
Your battery will last longest if used near room temperature, and nothing wears on a battery like extended exposure to high temperatures. While you can’t control the weather, you can avoid leaving your phone in a hot car or in direct sunlight, and you don’t have to carry your phone in your pocket, where your body heat will raise its temperature.
In addition, check the battery while it’s charging. If it seems excessively hot, your charger may be malfunctioning.
3Charge your battery correctly, in accordance with its type. Most newer cell phones have lithium-ion batteries, while older ones generally have nickel-based batteries. Read the label on the back of the battery or in the technical specifications in the manual to determine which yours is.
Nickel-based batteries (either NiCd or NiMH) DO NOT generally suffer from a misunderstood phenomenon known as the "memory effect." As described in Wikipedia and many expert sources,[2] the term "memory effect" has been widely mythologized to describe any and all deterioration of NiCd (and other battery chemistries), in many cases misleading consumers into further shortening the lives of the batteries through over-discharging to "recondition" them.[3]
[This section formerly read: If you charge the battery partially enough times, eventually the battery "forgets" that it can charge fully. A nickel-based battery suffering from memory effect can be reconditioned, which requires the battery to be completely discharged, then completely recharged (sometimes several times). The appropriate length of time between reconditionings varies. A good rule to follow for nickel-battery cell-phones is to discharge them completely once every two to three weeks, and only when you have a charger available. [4] ]
Lithium ion batteries can be preserved by careful charging and avoiding storing them at full charge.[5] They do not require "reconditioning."
Regardless of the battery type, use only a charger rated for your battery, and discontinue use of a charger that causes the battery to heat up excessively.

It's a shame most powerful mobiles heat up like nobody's business whilst on full chat these days.....there's no chance of keeping the batteries cool! Still, it's an expendable item and at least you can buy a replacement.....none of this iPhone 'sealed' tin rubbish.

while i find the battery life reasonable with the features this phone has (read screen size, processor speed), it will be nice to get the CPU throttling app another thread is discussing. don't need that 1000MHz running everytime i pick the phone.
On the same notes, how can i check if automatic screen brightness is kicking in?

Stick the phone under a bright light such as a desk lamp and cover the light sensor with a piece of paper.

are you the first wm phone user? Do you have good experience with phones that has so much specs? Do you use wifi and browse with phone very heavily? If you do, it is really normal that the battery will drain. My Touch HD does the same, it can last a day or 2 or drain like water not more than half a day, it depends on your usage. Try to get a second battery, or even the third one like I do, what is a big deal? It is completely normal.

I don't have a lot complaints on this phone as it meets most of my requirements.about the battery, I seriously don't think it is that bad. for example if you have a car with 1500 horse power and expect it to have or rather 30-40 mpg, don't think it is possible. try to use your local gas station (in this case your friendly charger) more often.move on with your life please.

That might be a little difficult because this battery problem is killing him, LITERALLY

Battery Charging Tips (Golden 100%)

Just want to share my experience of 'best' charging method that can maximize the battery life of my Nexus one.
Firstly, let me introduce my equip:
- Machine: Nexus one
- Rom: FRF91 Stock, Deodexed, rooted, busybox... (Geo411m)
- Kernel: intersectRaven's 2.6.35_AVS-925mV_CFS_20100802_1056.zip
- Control: SetCPU, Interactive: 245-960Mhz when on, and 245-245 when screen off
The key method of obtaining max. battery life is the 'GOLDEN' time from 100% drop down to 99%. Once the battery shows dropping from 100 to 99%, the dropping speed is quite stably fast onwards
So, how to retain 100% longer before dropping to 99%? Below are the steps that really work for me:
1) Charge the phone to green light, some where between 90% and 100% (say: 95%)
2) Disconnect USB charging cable
3) Turn off the phone
4) Connect USB charging cable and charge the phone, it should show orange light
5) Set a timer, remember to *ONLY charge the phone for around 20-25mins*
6) The concept is NOT to charge the phone until you get green light. In order words, you need to charge the phone from 95% for 20-25mins where the light is kept ORANGE with the phone turned off!!!
7) After 20-25mins, disconnect USB cable and power on your nexus phone
8) You are done and the battery should last longer before dropping to 99%
9) Time in step (5) depends, you need to trial-&-error
For my experience, I normally charge the phone before I sleep and disconnect the charger. In the morning when I get up, it usually shows around 95% of battery. Then, I power off the phone and charge it. And then I take breakfast, bla bla bla ~ and after around 20mins, disconnect the charger and go to work. The battery can retain 100% for around 30mins of continuous web browsing, facebooking... and when I reach my office, sometimes, the battery still shows 100% !!!
So, above is my experience of how to maximize the 100% retaining time.
Please feel free to try and share with us whether it really works for you

Great advice.
Personally, I can't really be bothered with going out of my way to be overly concerned about battery life. I don't play games on my phone -- that will change when Angry Birds is released for Android -- nor do I watch movies, and I don't really do too much web browsing. Sometimes I listen to music, but not often.
I can go 12-14 hours of normal use (mostly Twitter and text messaging) and that will put me around 45-50%. I'm never somewhere that I can't charge the phone if I need to; USB at work, regular charge at home, and a charger in the car.
All of these tips and tricks for extending battery life are neat, but why bother?

^ Well looking at your usage, and the plenty charging points, of course you dont care. However, some ppl browse a lot, play games, so every last inch of battery life means something.

I just keep spare batteries in my pockets =D

I will try your golden tips.. then I will write my thoughts.
I thank you for sharing.

Screwing up the battery meter does not get you more battery life, period, and I suspect your shenanigans here is doing that. The battery has a set capacity, it's not going to charge more than that.
The Nexus One and a lot of other modern phones with modern batteries DO NOT trickle charge, they charge to 100% and STOP charging. When the phone drops to a certain limit, it charges more. Repeat as long as it's on the charger. This is why you might see it "drop a few percent" when you pull the charger.

Yea this sounds like a huge placebo effect.

Well I just did this, been off charger for over an hour.. still 100% after over an hour and two reboots.
At 1378mAh right now, didn't get a reading straight after first reboot unfortunately.
I'm also trialing autorun killer. Disabled a free services I don't use.. seemingly increased startup time.

heya,
Don't you mean decreased startup time?
Cheers,
Victor

Yeah, that's what I mean.

How do you figure out your mAh level? Spare parts only shows me mV.
Thanks
Sent from my Nexus One using XDA App

This is placebo. In the OP you even say after it finally drops to 99% it drops fast after that. It's because the phone wasn't at 100% all that time. It was giving you a false reading from messing with the charging pattern.
The best way I've found to charge the phone is to delete the battery stats, turn the phone off, and charge it until it's green. I get a great day of battery life with the phone that way.

Totally agree...I just charge when & where necessary and never worry about it! Don't have the time and it seems to last long enough for me to work & play

I had already discovered this and was looking for a fool proof way but I guess you beat me to it. Happens when you traveling alot. For me, I have gotten over 1500mAh more than once..some times 100% would last me half a day too. So it's worth it, my question is whether or not this is bad for your battery? or long term battery life.

I had already discovered this and was looking for a fool proof way but I guess you beat me to it. Happens when you traveling alot. For me, I have gotten over 1500mAh more than once..some times 100% would last me half a day too.

I'm fairly sure that the Milliampere-hour (mAh) is the capacity of the battery (the amount of energy it will store). How can you get "over 1500mAh" on a 1400 mAh battery? None of you are making any sense what so ever. You can't get more energy out of a battery by charging it a specific way. If I gave you a bucket that held 10lbs of sand and you filled it with 8lbs of sand and waited a few minutes then started filling the rest slowly, it wont hold more sand. This is nothing more than a placebo effect. The only way to get more time from a battery is to reduce the amount of consumption. The only way to do that is to use your phone less or make your hardware use the battery less such as undervolting your CPU. I tried for the longest time to explain to people that underclocking your CPU does absolutely nothing. If you're still running at the same voltage you're still consuming the same amount of power.

Stop messing around with the battery and the battery stats.
Could someone please use the phone until it goes off in the evening? What percentage is shown on the batteryicon when it goes off? 20% or what?

Actually it's not a good idea to fully discharge the phone often.

I know but once isnt often.
Btw we have some great battery threads here.. somewhere.. general or accessories forums..

I have been using ultimate juice defender and battery life has doubled with usual usage. Maybe this can be considered as an alternative to longer battery life

[Q] Does battery get better after a day? If not, what can I do?

So I got my G2 yesterday at about 4:30. I LOVE it, absolutely (a bit of a weak hinge, and I had a random reboot and trouble starting WiFi at first, but it's seriously fantastic). But I'm having problems with the battery. At the store the guy turned it on and handed it to me, and I used it on the way home to the point that, by about 1.5 or 2 hours after turning it on the first time, it was at about 15% battery. So I started charging it, and then read an article online that it should be discharged, so I unplugged it after it went up about 4 or 5% in battery life to 16% and used it a bit more to drain it all the way. Then I read a different one saying you should never discharge it because it's Lithium Ion, and so I turned it off until I could get to the charger and then charged it and left it charging until I woke up at 6. Then I unplugged it, used it for about 20 minutes in the morning, and turned it off. I turned it back on at 3 today, used it mildly (Angry Birds, an emulator, and the camera, but couldn't get data access except very intermittent EDGE, no Wifi or GPS enabled) until 4:10, and noticed that it was at 65% battery life. The screen is on automatic brightness, and I have animations and a live background, but those are my only concessions. It said 45% of battery use was Android and that was the highest thing, I think display was only second or third (unlike my parents' Vibrants where it's like 66% display).
So that's 1.5 hours for a third of the battery, with moderate usage (I would argue that no data or GPS or wifi or internet usage at all is very moderate). So, on average, I could expect to get 4.5 hours of battery life? At one point it went from 55m unplugged to 1:07 unplugged and the battery went down about 10%. That's worse than my parents' Vibrants, and they say they didn't do anything to train their battery--and I've seen reports, especially on here, of people getting 10 or more hours of use with more usage than I had. I know you train Android and not the battery, but still, I have seen SUCH conflicting information on this that I don't even think it'd be helpful to search anymore (and trust me, I have). So does anyone know about this, definitively? Does the battery life get better after I charge it and discharge it for several days? Should I let it go down to a full discharge or keep it above 35-40%? Does it harm it to keep it plugged in after it finishes charging, or does it have a thing to stop charging the battery and just run off AC once it reaches 100%? Is it too late to train my battery now? Are there any official or reliable large-capacity ones for the G2, like a 1750 mAh?
Thanks,
Rocky

Don't trust the battery meter. Fully charge your phone up, and it runs for forever. I've gone days where I unplugged it at 7:30 AM, and didn't plug it back in until 5:30 AM, and the battery was still above 20%. That was a day of fairly light usage, so that's not necessarily typical; with my normal usage (which is somewhat heavy), it's at about 30% by the time I plug it in at around 10:00 PM. The only time this isn't true is when I go for hours on an Angry Birds marathon :S

I have noticed on all my android phones that the first couple charges seem to drop much faster and each subsequent charge seems to get better. I run mine all day with push work email and vibrate all day and am upset when it is below 65% at 10PM and I unplug it at 7:30 am each day.

But did you guys do the same thing I did (15% then charge overnight) and then get around the same life, on your first day? Is it likely my short charge the first time did any damage? And are there any apps to provide a more accurate battery meter, preferably in place of the stock one?
Thanks,
Rocky

I did nothing special. I put it on charge when I got it but did not do a full charge before leaving work and going home. Did a full charge that night.
I plug it in each night when I go to bed and it has been as high at 70% and as low as 30% depending on how much phone and data time I spent that day.
I unplugged mine today at 7:36am and at 4:06PM it is at 79%.
I use battery indicator from the market. It does not poll and only listens for the OS battery change broadcast so it does not use up battery by running. Some poll and as such use battery to report.

The general thing about Lithium Batteries is that a full discharge is bad if the voltage level goes below a certain point to where the onboard circuits will disable that battery permanently. Most of the time the boards only do that if it's left discharged for a long time I believe, correct me if I'm wrong here.
Ideally, you're not supposed to turn on the phone when you got it. You were supposed to charge it till green and then you could use it, but I'm pretty sure not everyone can resist the temptation to turn on such an awesome phone . The battery life will blow the first week of use. I don't know why, but it just does; you'd have to break in that battery. Then the general rule I follow is to perform a full discharge once a month and then do a full recharge.
I also placed my phone on GSM AUTO PRL but for doing that I just exchanged some low 3G signal threshold for Edge; the extra battery life I got though is just that much more useful to me. Using WCDMA Preferred, the phone just wasted so much
To answer your questions, my experiences with the N1, Vibrant, and G2... battery life just blows in the beginning but gets better with use. The first charge you did shouldn't have damaged the battery but I think you may have wasted 2 of the possible 400-500 cycles that battery is capable of doing what you did. Finally, I use BatteryTime by Motalen for the status bar battery indicator which shows the % left.

Yeah, it just sucks because the guy at the store literally put my SIM card in and then turned it on and handed it to me. I probably wouldn't have turned it on until it had charged if he hadn't, or at least I like to think so.
So it's good to do the discharge thing once a month, and probably not bad for the battery to let it dip down as long as I don't prolong it too much? And I'm okay to just charge it and use it during the day, basically, from now on?

Does battstat poll the battery or just listen?

Nonsense. The battery runs down fast the first week because you got a new toy and you can't help playing with it all the time. After a while the novelty wears off and you use it a lot less. The battery doesnt just magically get better

See but if that's true then I can only expect 4.5-5 hours of battery life which is not what the G2's supposed to get. Which means either I DID mess up my battery instead of just running through some cycles, or I have a bad one, but not horribly bad, just for some reason only like 60% as good as everyone else's. I do agree about the novelty thing (it's my first smartphone), but understand I was not really doing all that much when I drained my battery like I said. Not nearly as much as it should take.

I'm hoping that's the case. I remember receiving my N1 and I got to relive my childhood days for 12 straight hours. Regardless it's pretty sad to say that I leave my G2 at home while at work and it's down from 100% to ~60% with Wifi on (and with it staying on in the advanced settings) and GSM Auto PRL; I work a 8 hours shift. I left my N1 at home to mess with my G2 at work and my N1 went from 100% to ~80%.
Those 100 extra milliamphrs shouldn't do that much of a difference. Not to mention the N1 is slower and on a 65nm process. Did I also mention that both my G2 and N1 run the same services and 3G is also disabled on my G2 since I don't have my new SIM activated yet? Also, Latitude is always on for my N1.
It's just my experience though. I'll give this a good thorough test when I get the time. That or pony up for an extended battery.
On the other hand, my wife's GalaS is doing just fine in terms of battery life. Matching my N1 with the same settings and services.

Battery charging wear

Didn't find a main thread for silly questions such as this so hope it wasn't wrong for me to post this here, but I currently find myself in my phone going as low as 50% on a daily basis and I charge it next day at not lower then 40%, will this wear out the battery? am I really supposed to charge it when it's really low? Thanks.

The latest in Li-ion batteries, as the one in our phones, one duty cycle is when you use 100% of the charge.
That is ifyou go from 100 to 0 that's one cycle.
If you go from 100 to 50, recharge and again 100 to 50, that's one cycle.
Batteries wear out depending on the number of duty cycles. More duty cycles, more wear.
So what you are doing will not wear out the battery.
Also I'm not sure about this, but it is recommended that newer batteries should not be completely discharged.
Please correct me if I'm wrong, anyone else who can confirm.

Modern batteries are not like older (10 years+) batteries. I'm not about to write a wall of facts here etc. etc, but I only have one thing to tell you:
Use your device, and don't worry about the battery. It'll do just fine until the day you decide to buy a new device. Now stop worrying and just use it.

Same here, these batteries are tough. I am anal about my phone battery being charged. Haven't had an issue for years and I expect the same performance out of my S7E

Topping up your battery before it is fully discharged is the best way to extend your battery life. Modern batteries run best between 40%-80% charge. Minimize the number of times you fully discharge the battery as that is more likely to wear out the battery, although it is ok to use it until the phone shuts off once in a while.

Very impressed with the battery of the S7E. I charged to 100% last night and didn't charge until just an hr ago and was at 47%. Normal use in the morning til now. In n out of meeting, so its doing its job.
Now back to the topic of this thread, i've read some say these newer batteries should be power cycled at least once a month. Any one recommend that or against it? Haven't done it myself but did it a few times on my iPhone 6 Plus and that thing had an awesome battery even though its actually smaller than the S7E. Thoughts???

I've seen it recommended as often as once per month or as infrequently as once every 3 months. The general consensus is that it can be beneficial in that it can correct any issues that the phone software has in determining the battery's capacity, not that it is actually helping the battery itself.

Yup, I did that once in a while with my previous device (a Sony), and the battery on that one is still very good after nearly three years. I wouldn't do it that often though, but it's useful to do it when you notice the battery meter hangs on the lower numbers (like if 10% hangs for an unusually long time) or you've just flashed a ROM. The OS tends to get a little confused after some time, so it's okay to do it to "calibrate" the system again.

Thanks for the helpful replies guys.

Draining a Lithium battery to zero is one of the worst things you can to an Li battery. Don't do it. Period. Ever.

Yes, don't power cycle a battery. It MAY help give a more accurate battery reading, but it's messing up the longevity.
