Hei,
Ever since i saw this thread, I was considering a better battery for my legend.
To begin with the stock battery (Standard HTC battery) that came with the phone.
1. It used to last me for 2 hrs 10mins of voice call
2. If GPS was on it takes about 25mins to fully drain from about 95%
3. between 80to40% whenever screen was switched on, phone used to heat up.
4. At times (lately) even when the phone was in stand by in my pocket, it used to heat up so badly, i had to refrain from keeping the phone in my pocket. It actually felt like a "hotpack" in my pocket.
Phone is just perfect except for the retarded battery that comes with it. Whats the use an awesome phone if it you cant go through a day of light to moderate usage without requiring a charge?
So i decided to try out the mugen power batter. I love my legend, so even though battery was a bit pricey about INR.2,153.00 (USD46.95) (after shipping). I ordered a mugen battery 1800mah from their official website on 8th Nov. They took about 14 days to ship it to India from Hongkong (3 days waiting as batteries were out of stock).
Received it a week back. and currently i am running the 4th recharge cycle.
Immediately installed the battery on receiving it. (Couldn't wait!!)
The battery came with instructions to fully charge the battery (even after its fully charged as indicated by the green LED on phone) for 10-12 hrs for each cycle and nearly drain the battery before charging it again. (I took it to 5% each time, charged for a minimum of 11 hrs)
The fit
I was dead scared seeing the comments in this thread. But the battery was a perfect fit, infact the same fit as the stock battery. It would directly slide out without any poking / fingering
Tip - There is a small red plastic stick in the battery compartment to assist in battery removal. I dont have to use it though
The following are the actual statistics i have written down after each cycle. (Help me post a screen shot pls)
Recharge cycle 1
1st charge for 12hrs continuoesly
Voice calls 29% - 45min 44 sec
wifi 30% - 7 hrs 22min
Display 27% - 2hrs 12min (full brightness for 1hr)
Mpas 8% - GPS -23min, data 10mb
cell standby 4% - 7hrs 22min
phone idle - 2% - 5hrs 12mins
Total 7hrs 22mins from 100% to 6%.
Dint record the 2nd cycle, but was difficult to drain the battery in the next 13 hrs, had to switch on GPS + music on for 30mins on speakers + torch app with about 80% brightness for 1 hr to drain it before 11pm the next day.
I wanted to charge battery for atleast 10 hrs before leaving for office
Recharge cycle 3 Unbelievable!!!
3rd charge for 11hrs
Voice calls 12% - 1 hr 15min 12 sec
wifi + bluetooth 44% - 37 hrs 12min (dint turnoff bluetooth/wifi) transferred about 153mb in this cycle
Display 17% - 3hrs 12min (played angry birds for 1hr!!)
Mpas 13% - GPS -14 hrs 12min, data 43mb
cell standby 9% - 7hrs 22min
phone idle - 5% - 5hrs 12mins
Total 37hrs 31mins from 100% to 4%.
As you could see there was a drastic increase in battery performance after the 3rd recharge.
------------
Note - I am using juice defender (free version) + the phone is on strictly GSM only mode. (Exhausted my monthly data quota on 3g )
Currently I am charging it for the 4th time. Will post the final results again.
Also as froyo users are posting better battery performance, expect even more longevity of the battery once i receive my OTA (damn ever eluding update)
Conclusion - Definitely its a drastic improvement from the stock battery and the best part is it resolves the only problem i had with my legend, heating of the phone for no reason!
Makes me wonder why legend doesn't come with such a battery on default purchase.
Thanks Mugen for such a great battery
Do drop your comments and suggestions below or any standard benchmarking tools that i can use ...
Review part 2
< Reserving for 4th, 5th and final cycle >
Heating up is unusual with legend under normal usage, are you sure it has to do with the stock battery?
Some people did report problems with juice defender, your case may be different though.
Gotta say mugen battery was very lasting initially if you follow their instructions properly, but after using it for couple of months I don't think iam getting that same performance, its much less.. though still better than the stock one.
My mugen fits lil tighter than the stock one, its hard to get it out without that red lever. Iam kinda surprised about yours being the same fit as stock one. Dunno if they changed anything.

No heating issues at all after replacing the stock battery with the Mugen one. Havent changed / installed any new apps / software for the past 2 weeks. 1 week with the new battery.
So i can confidently say the stock battery is the culprit.

Hope mine gives the same performance at a later stage as well. Can it be that you got used to the longer battery life and dont realize it now?

I dont know if they have made any changes to the battery. My Mugen slides right out of the slot on tilting the phone after opening the case just like the stock battery!

It could be that, but iam sure it doesnt last as long as it was initially.. but still better than the stock one for sure.

Mine doesnt slide right out like the stock battery, it does need lil effort. (ie. the red lever) May be they made some changes after selling many pieces ?

I've experienced the same short life when charging through USB, but when I use the wall charger, it lasts much longer.
Going to bite the bullet & try out one of these, just awaiting the money to be put in my PayPal account.
great review..pavan
I would like the link to official page exactly where u did shop and also the detailed battery product number which we have to select...I am from Mumbai..

I purchased the 3500 extended battery about 4 months ago. It was a great battery. It lasted me all day & then some off a single charge. Now it's not lasting as long as it used to. I'm having to charge in the middle of the day now. I put my original OEM battery in, & I'm getting better performance from it than with the 3500 battery now.
Anyone else experiencing less than stellar performance from the 3500 battery after having it for 4 months or longer?

I have the 2150 OEM, I can only suspect some reasons why
1) Cheap battery that does not hold charges well
2) You are draining the battery down to 0% a lot, killing the ability for it to keep a charge
3) Your phone is not calibrated properly so it shows it is charged to 100% but in fact it may have only charged it much lower

1) It's a Seidio brand, not some knock off, so it should be of good quality. It's been working fine up until the past month or so. I've had it for over 4 months now.
2) I've never drained the battery down to 0%. Contacted Seidio and they suggested that I let it drain to 0% for the next 4 to 5 charges, along with charging it an additional 2-3 hours after a complete charge. I'll see if that helps.
3) I've always had to bump charge it. It helps in making it last longer.
I don't think bump charging is helping the longevity of your battery. Not saying it doesn't last longer on a charge, but that it isn't good for the battery's overall lifespan.

Draining all the way down and overcharging it are the biggest ways to kill it off. The Seideo and most other batteries I think have a fail-safe for draining it all the way down, cutting it off early before it actually does.
This article is pretty helpful about your battery, if you haven't had the chance to read it, it may benefit you:

Bump charging did it.....
Where's ma rosie at?
I have been using the 3500 for about the same length of time you have been. I haven't really noticed a drop off in performance. Maybe a very slight drop off.. not much though. Still could get 2-3 days use on one charge if I wanted to.
I have the same issue with my 3500. I will try to re-calibrate it.
4 months seems to be pretty quick for a decline in performance like that. I would press Seideo to replace it.
You can try resetting the cells to how they were when it was brand new. All you have to do is completely deplete the battery of all charge (so it wont even turn on) then short it out with 3x the voltage (a 9v battery should work, make sure to keep the polarity the same) and fully charge it again, then it will be like new!
My dad (who is an electrician) found a guide for this on ebay and bought it just for the hell of it to see if it worked. We tried it on a battery I had for an LG VX8300 I had at the time and it worked beautifully, I've been doing it ever since!
I have no idea how this works, all I know is that it just does.

When ever you get a new battery you must condition it, exactly as sedio said full charge it, then drain fully 5 times. It makes the battery last much longer

I got some 3,500mAh cheapies off ebay about 6 months ago and they are holding up just fine. I always run mine down to about 5% then fully charge. I bump charge them about once a month.
Well of course... After I'm pimping how great these batteries are, one quit working! My phone would just shut off with a light tap against something so I pulled the black sticker off of the battery, pulled it all apart, found the loose connection, bent the tab to make better contact, and put it all back together. All is good again.
I recently purchased this same battery read tons of good reviews not sure how i feel about the bump charging after reading the article that was within this thread but all in all it is a giant leap beyond the stock battery now if i could just find a case that would fit around it
To the OP. If youre running a kernel with SBC (Superior battery charging [trickle charging] w/e you wanna call it) they're known to reduce your battery life. also you may wanna charge the battery to 100% then wipe the battery stats on your phone.
I have the same battery and I've found that the phone has trouble reporting the percentage correctly. It tends to make jumps of about 5-10% instead of a steady decline. I switched to the original battery and it did not have this problem. I've also noticed that clearing battery stats several times helps (most of the time). As far as bump charging goes, it's perfectly fine to bump charge these batteries. The worst thing you can do to them is discharge them all the way.
Clearing the stats and cycling the battery through the phone a few times should fix that. It does that (big percentage jumps) when it's poorly calibrated.

I second this. I have the same battery and its been off a few times. Battery stats get weird sometimes. It's certainly a better battery than the cheap Chinese batteries HTC uses.
So I'm burning 1.8% per hour according to BBS. Does anyone here know how to decipher the info and tell me what's the culprit?
1.8% per hour? That's not even bad. Round it up to 2%. That's 50 hours. What's wrong with that?

It may be likely that your Moto X’s battery is fine, but having trouble correctly identifying how much battery life is left.
Simply run the battery down to about five to eight percent and let it die. You can speed this up by streaming a YouTube video. Then, when the Moto X has died, let it charge for a few hours before turning it back on.

Never go to zero
Obviously, using your battery is going to make it degrade. But it's going to slowly die even if you just leave that iPad in the closet for a bit. There's a trick to minimizing that inevitable aging though: leave it a little bit of juice.
If you're going to be shelving any lithium-ion battery for a long time, try to leave it with at least 40 percent battery power to tide it over. Lithium-ion batteries don't hemmorage power at 30 percent a month like nickel-metal-hydride batteries do; they'll lose maybe five to ten percent of their charge each month.
And when lithium-ion batteries get too low—like, literally zero percent—they get seriously unstable, and dangerous to charge. To prevent explosion-type disasters if you do try to charge one, lithium-ion batteries have built-in self-destruct circuits that will disable (read: destroy) the battery for good, if it reaches rock bottom. And sure, that'll save you from a face full of battery-acid, but it'll also leave you short one battery.

Always have heard it is bad to drain the battery in a phone. I know other people swear by it, but its not worth the risk of it not charging again, or worse blowing up.
Charging sooner doesn't hurt since there is no "charge memory" like nickle based batteries. so just plug it in when you can, and if you your away from an outlet for too long, maybe it time to consider an external battery backup.
OP, here's another thread that has been discusing the same issue, its a good read.
http://forum.xda-developers.com/showthread.php?t=2418077
I burn around 6% after the last update, with no other changes to the phone. And that's with Battery Saver on too. Used to be around 1.5 to 3%. Everyone said "just wait, this always happens after an update, it will eventually settle out". Total BS. My daily battery life has been cut in half for months.
Well I did a better battery stats 6 hours test ( let it sit no touching etc ) and Im only at 1% an hour. Im pretty happy with that.
I've tweaked the crap out of my phone....and get 24+ hours with 5 1/2 to 6 1/2 hour screen times. Extremely happy......and best I've got on standby is 1ish per hour.
Again....tweaked the crap out....for battery life. LOL. So 1 percent even may take sacrifices some may not wanna make. I'd say a stock sorta phone would get 2 even and you'd be doing alright.

wow you guys are getting great battery life! According to GSam Battery Monitor, I'm at 9.7%/hour. Currently 6 hours since unplugged and I'm at 35%! With only 2 hours of screen on time.
I think I messed it up when I first got the phone. I immediately upgraded to the 2 OTA's and forgot to do a factory reset. I think I might do one now and see if it fixes the battery life.

1 percent per hour is with no use. 9.7 per hour with you using it a lot and depending what you are doing could be perfectly normal.

Is it a myth or truth, that it will help my battery life if I completely drain my battery down and fully charge it up? I've yet to do this in the 2 weeks I've had this phone. I know it was the case many years ago and not sure with todays batteries. Something about building up the battery memory. I'm down to 23% as I type this.
google is your friend sir. that is only for the old NiCad batteries. from what ive read you actually dont really want to completely drain any battery because it becomes unstable at that point. the main tips are to keep it cool. top it off when you can, most say to plug it up around 50 %, dont leave it on charge forever. and dont extra load the battery. ( some people take it out at 100% and plug it back in to get the most juice out of it)
Some recommend it once a month, and some do it every other months. One time doesn't hurt
I for the last 5 years or so have never done any of that and can tell you I never have had issues with my battery
BAD ASS NOTE 4
Haha Anyone that tells you that it is good or makes a difference to totally discharge a battery and then charge it to fill will help the battery doesn't know what they are talking about. Only the old Ni-Cad (Nickel Cadium) batteries developed memory and needed full cycle discharges. The new batteries that are in phones Li-Ion (Lithium-Ion) do not develop a memory. In fact these batteries have a number of cycles before they go bad. Batteryuniversity.com explains that routinely charging a battery when it's under 25% will yield roughly 300 or so cycles (charging to full). At 50% remaining Battery you will get 1000-1200 charge cycles and charging the battery when 75% remaining you can get as many as 2000 charge cycles.
So the point is never let it drain all the way, and charge frequently. My Note 4 gets about 8-10 hours of screen on time and my average days I have about 2-3 hours of sot and charge my phone 70-80% battery left. My note 3 was the same and had it for a year and when I sold it a month ago. I was still getting the same battery life. Maybe 3-5% more drain from when I got it.

Yup. Same here. I charge the battery whenever I want... And let die if it has to. Plus, it's the enclosed battery users that should worry about that.
Hey,
Finally I bought this beautiful phone and used it for couple of days but I'm not verry impressed with the battery life
I only get 4:45 5 hours of screen on time
Is this normal?
What is your opinion about this?
There is a battery life thread already. Go there and read it. You'll find plenty of opinions.
SOT is a nonsense way to measure IMHO.
As it would really depend on how one uses the phone.
I get anything between 5- 8 hours SOT depending on what I do.
120htz, 5g, Bluetooth and screen brightness on 50%
Rest is all auto or adaptive.
Working days I come home with around 70% battery and them try to deplete it by playing COD and stuff in the evening and still have 40 -30 % left.
I do charge overnight regardless how much battery is left as I like a full battery in the mornings.
