If you have a look at Mugen’s HTC Hero Line-up, they currently have 2 different Batteries available:

• Mugen Power 1550mAh Extended Replacement Battery: a standard-sized, stronger Battery, that fits in the Hero without the Need of an additional Backdoor
• Mugen Power 3200mAh Extended Replacement Battery For HTC Hero (GSM) with Battery Door: the king-kong sized Replacement, which is powerfull, but needs a separated, much thicker backdoor. the problem here is, that the device looses it’s slickness, becoming a brick in your hand.

Part 1 of my Battery Test was performed in daily Usage, in the Conditions i normally use my Phones in. I’ll going to perform some more Tests under more power-consuming Conditions soon – in the Meantime, here’s the Settings i’m using in daily Life:

• 3G: off, phone only on EDGE, but permanently online
• Bluetooth: on
• WLAN: used whenever available – roughly 35-40%
• Mail & Twitter checks: every 5 minutes
• SMS messages: approx. 50-70 everyday
• Calls: approx. 2h every day
• Internet Surfing: around 1-2 h everyday
• Active Playtime with the Phone (Device not in standby): 50%
• some occasional App Tests, Camera Shots and seldom some MP3s

So, without further ado, here’s the Results of the first Test – all from full Charge until the Phones gave me the last 5% Battery Warning:

• HTC Stock Battery 1350 mAh. – 12 hrs. 15 minutes: As mentioned a few Times already, i doesn’t get much more than a typical Workday from the standard Battery. I get up at 6 o clock, working from 7 till 5, and usually about an hour later, i have to put the Hero on the Charger again.

• Mugen Power 1550mAh Extended Replacement Battery – 15h 5 minutes: almost 3 more Hours for the standard-sized replacement Mugen battery. this is pretty much what i was expecting for a battery with only 200 more mAh, yet it’s a bit more power for a reasonable price of just € 20,66 and the HTC backcover perfectly fitting!

• Mugen Power 3200mAh Extended Replacement Battery  with Battery Door – 37h 20 min: Yes, you read right, 37 HOURS with this Beast. The big 3200 mAh-powered Battery get’s you through 1 1/2 days on the same condition as the other Batteries, 3 times longer than the others. But, here’s where you have to decide: More Power and a thicker Phone or less Power and go with the slick, stylish Hero Layout? It’s up to you – i’ve prepared some Comparison Pictures for you, so you can see how much thicker your Phone gets with the Mugen Battery Door! The 3200 mAh Battery is currently available for only € 55,14!

I haven’t done the heavy Test yet, but so far i can say that Mugen has absolutely delivered the Power they have promised, which definitely is a blessing to all of us under-powered Phone Users, for reasonable Costs!

Anyways, Friend of the Site Micky Aldridge on Nokiausers.net has already tested the extended Battery Options for the N97 and the results were amazing to say the least. I’m also in testing mode, working the 2 Batteries on my HTC Hero and so far i must say, Mugen does not fail to deliver!

“Mugen Power is working on Extended Battery for N900 and will be releasing a 2300-2400mAh battery in February 2010. You can use following rss feed to be updated when the battery is available: N900 RSS.” – as stated on their Website! This is great News for every N900 User and i’m 100% sure you will not be sorry to spend a few Bucks on a great Battery!

With Mugen Batteries it’s different, because Mugen stay true to what they’re saying. Friend of Site Micky, from the highly recommended Nokiausers.net has recently put the same Test on his Nokia N97, using both the 1800 mAh Extended Battery plus the bigger 3600 mAh Battery, which comes with a separated Backdoor, as your Device can’t fit it in with the default Backdoor! I won’t spoil the Results here – if you want to check out how those 2 Beasts performed against the N97′s 1500 mAh default one, check out Nokia N97 Mugen Extended Batteries – Conclusion over at Nokiausers.net!

So whats going down here in the upcoming Days/Weeks?

• My Standard 1350 mAh Hero Battery – not too impressive honestly. With constant online Times, using Mails, Twidroid, often checking Facebook and Newsrob etc, i don’t get much more than 10-12 Hours. And this is with Bluetooth, 3G and Auto Screen Rotation being switched off, just for the Record. This Battery will go head-to-head against:
• The Mugen Power 1550mAh Extended Replacement Battery: 200 mAh doesn’t sound too much extra Power, but if you check out Micky’s Article again, you can see what 300 more mAh can achieve: Nearly DOUBLE as much Go-Time on light/medium Usage and almost 3 times better Performance on heavy Usage. Not enough for you?
• Then the Mugen Power 3200mAh Extended Replacement Battery For HTC Hero (GSM) with included Battery Door should be just right for you! First off, this Battery comes with the Battery Door, cause it simply makes your Device thicker. That much more Power of course needs it’s Space, so this Step is neccessary.  I’m not 100% sure yet, but i’m used to bulky Devices, so i’d be happy to have a bit more Phone for the Price of getting a lot more Battery Life – which you DO get, judging from what i’ve read so far! I won’t spoil no Results yet, but the Improvement should be big!

I’m REALLY looking forward to test those Batteries in my Hero and give you some first Hand Reports, about how much better the Performance with those Batteries get. A big THANK YOU goes out to Mugen for agreeing on the Test Batteries and in the Meantime, feel free to check out Mugen’s Shop by hitting the Picture down below!
