I thought I would share the feedback with you guys !
Mugen Power is a 3rd party battery manufacturer, and is known for it's "extended" batteries. If you’re an owner of a high end Android phone you too are probably facing a very poor power backup with the stock batteries and that’s where extended batteries come into play.
Basically, Mugen promises something near double battery life with this extended battery life, let's see how this extended battery fairs.
This battery comes in a very small, compact and simple backing - it has a leaflet with the instructions and standard warnings, a back door and the extended battery itself.
Look and Feel
We already know the HTC Sensation is not a very thin device in itself, and by adding the Mugenextended battery and the battery door, it does get noticibly thick - but for double battery life which it promises, the thickness can be bared - at least for me !
One would think that this battery adds a significant ammount of weight to the phone, but on the contrary it does not add any weight which can be significantly felt.
It's also nice to know that the backdoor cover fits perfectly on to the Sensation, and the feel of the replacement cover is not different from the stock one
However, with the extended battery users with small hands will find it a little difficult to hold on the phone for long durations at a go, rest shall be fine.
The li-ion extended battery which we were provided was rated at 3600mAh which is more than double of the stock battery on the HTC Sensation which is 1560mAh, so was the battery life also double ? Let's find out.
I have been using the HTC Sensation for almost 2 months now and with moderate usage, casual browsing, push email and constant interactions along with a lot of IM and calls, it did last me around 11 hours or so with moderate usage.
But on days when I had heavy usage, with constant data transfers on wi-fi or 3G along with lot of media playback, games, calls and IM - going beynod 8 hours was a tough task for the Sensation.
Now I did spend a nine days on the Sensation with the Mugen Power extended battery, and yes, it works ! And works pretty well following are the figures :
Heavy Usage : 2 days
Moderate Usage : 3 days
Light usage : 5 days
Now let me describe my usage, my heavy I mean constant connectivity either via 3G or wi-fi, 5 email accounts with push email and mails coming in every hour or so on all 5, constant IM i.e. Google talk and Facebook chat, off and on internet browsing, around 40 pictures shot, around 3 hours of voice call, lots of media playback (songs) and even video streaming.
My moderate usage I mean, data connectivity on 2G and wi-fi, push email, selective IM, and 2-3 hours of voice call, with causal browsing and media playback.
Light usage is more like a few texts, some casual browsing and a few calls in a day, with hardly any data usage - more like constant standby.
The Mugen battery is a very good buy and lives up to it's promise of increased power backup. It is a must have for hardcore users and the people who travel a lot, regardless of their usage patterns.
One would however have to bare the slight increase in the thickness of the phone, but amazing amount of backup one gets is well worth it.
But, if you are a light user, and mostly have the phone on standby with a few calls a day, Mugen Power is not for you.
Also note that the HTC Sensation has been known for the "Death grip" issues - but don\t worry the added thickness or the replacement door on the Mugen extended battery does not affect the signal receiving capabilities of the HTC Sensation.
Overall, the battery lives up to the promise of double battery life and has left me much more mobile fearless about the phone battery finishing suddenly !
