Mugen powerbattery 1800mah for legend full review

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!

Good luck to you
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.

battery life

hey guys
in the last couple of weeks ive flashed about 5 roms which consider to be good.
i have to say I really like android but one issue keeps me frustrated
and thats battery life.
how can it be that my friends iphone battery lasts so much more then my galaxy s1?
ive gone through numeros guides decreased brightness to minimum
stopped syncing my gmail account and other stuff as well.
as time goes by im regreting not buying iphone when i had the chance
because battery is one of the most important things in a smartphone.
currently,
i am 25 years old student studying computer science in the university
which means im out most of the day.
its not that rare for me to be stuck without battery and its so frustrating.
i ask for your help please,
what is the best rom for s1 regarding battery life
and has hebrew on it?
(im from israel)
thanks alot mates!

Have you ever calibrated it after flashing?

Dropping to 0% is the worst thing a LI-ION battery can experience.
There are some calibrations methods around, you can try some apps but I think you ROM just needs some time to calibrate the battery sign. Are you running a zillion of apps in the background?

Another option is to buy a new battery with more power. stock battery has 1500mah. but you can get a battery with 1800mah for your s1.

Did you wipe battery stats in cwm?

Disable mobile data or switch to 2G only it helps a lot. Phone will drain battery if you have a bad signal

I have to second the disable the data connection recommend. Also your battery life will get better the longer you use a rom and the more charge/discharge cycles your battery sees. To be clear that does not mean 100%-0% every time just regular charging.
I'm personally on GB and with data disconnected for most of the day and the 1800mah battery I have been on the same charge for almost a week and still have 30% left. It's truly amazing!!

Dropping below the minimum voltage is what you're talking about, and that's not possible because of the controller on each battery. That's why the phone dies when it hits 0% (or thereabouts) even though it still has plenty of power left over to run the device. Running a full cycle on the battery will be just fine.

draining the battery

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.

Battery Drain is V.Bad Need HELP....!!!

I hav bought a secound hand oneplus 3t and hav been using it since a couple of weeks i have a lot of battery drain when the phone is sitting idle jst like browsing chrome or something . Some of the examples of my drain is charged to 100% and after 32 min of use the battery drops to 80-83%
i have tried almost all the custom roms and the stock roms I get only around 3-4hrs sot only on the stock marshmallow rom i hit 5 hrs need help
really bad.

You'll need to provide a bit more info to figure out exactly what's causing the drain. Download BetterBatteryStats, that will allow you to see which Wakelocks are involved.
Also, how old is the phone? Considering the usage and charging habits of the previous owner, its possible the battery itself might have degraded since batteries do degrade over time.

To do that, for an accurate reading you'd euther need a multimeter or any other capacity meter, but i believe you'd have to open your phone up even if you did have one of those devices since the battery isn't user accessible.
However, you can also use apps such as Accubattery which give you a similar reading. It wont be as accurate but it'll give you a general idea.

Dead battery!!!

Hey, got a weird issue with my device.
Just 4 years old piece and already this has a dead battery!!! Cannot use it anymore basically... drains overnight on airplane mode from 75-80% to 0 in 7 hours!!! Last night I left it fully charged and shut down just to not starting anymore this morning because there is no power left, battery is EMPTY!!! Just barely started to charge!!! Something is wrong with this phone, really wrong!!!
I tried custom roms but the phone has the same behavior... so I came back to MIUI 12.5 just to be in the same position and to have the same conclusion: I HAVE A DEAD BATTERY!!!
I went back to my old Redmi Note 5 Pro with a custom rom... just like knew. How is this even possible??? An older device, with same amount of use have a better battery life than a newer device??? Different battery manufacturer, some production flaw in the battery production? Either way, conclusion is clear: NEW BATTERY... so, so disappointed by this situation...

Batteries get old and die , you have to change it , or maybe there is a short circuit on the motherboard , best option is to take it to a repair shop

I know.
But I found out that in fact my phone is only 2 years and 3 months old??? So, is this battery old enough to die? I guess there is something else here.
In the meantime, I already change the battery, sadly not with an original one... and so far so good, but only a few days passed. This battery however is acting strange! Does not charge more than 86%. Aida64 reports battery full at this precent... but I guess time will tell if I made a bad/ good choice.

encounter the same problem after 4 years of using redmi note 8 battery drains so fast unlike before and changing the battery to a new one it either does not fully charges it to 100 percent and it shutdown when my battery percent is around 20 or so percent but when I try to connect a charge and remove it, it will open up to that 20% or so percentage and continue to be used, I'm guessing the it need a battery calibration but I know really know what to follow on the internet.
