HTC Desire Mugen Extended Battery 3200mAh

April 11, 2011

Still not quite ready to do the test yet as I am being patient and waiting the recommended 5 cycles before the battery is in it’s best state.

It’s quite frustrating really. I’m charging over night for at least 8 hours and then running the battery down to around 15%.

This is not as easy as it sounds. I’m having to leave the display on all day on full brightness with every feature the Desire has turned on. 30 minute timeout on the display and even whilst playing music too. This is as much as I can do to drain the battery. At one point I even left Reckless Racing on and running for a couple of hours to boost the drainage!

So far this looks well for the Mugen battery as it’s taking so long for me to discharge it to as low a percentage so that I can recharge it fully (hope that makes sense). If it copes half as well as this when it’s ready to use then I’m thinking that there’s a huge improvement with this battery over the stock HTC one – which is to be expected as it’s more than twice the capacity.

Two more cycles to go and I can be ready to do the full test and see how long the phone lasts with the new extended battery.

I suppose to make it a fair test I should downgrade my firmware back to Froyo 2.2 and then I can compare it fairly to the previous test I did.

Android App Test: JuiceDefender HTC Desire Battery Test/Tips

February 3, 2011

Today I’m going to best testing out the excellent little app JuiceDefender to see just how much battery it can save me on my HTC Desire.

Usual phone settings apply (see below). JuiceDefender running with default ‘out the box’ settings.

Here is how my HTC Desire is configured:
Fully charged at 9am.
Screen: Medium brightness (auto brightness off)
WiFi: ON (Wireless N enabled but will not be used at work as we currently only have 802.11b/g)
Syncing: ON (2 Gmail accounts and FriendStream – see below)
Bluetooth: OFF
GPS: OFF
FriendStream: ON (Twitter updating every 15 minutes and Facebook every 1 hour)
Wallpaper: Set to Live as per the previous test but didn’t mention.
2G/3G Data: Enabled  with network mode set to automatic and data roaming enabled

I’m going to compare the battery level with my previous Froyo test to get a rough idea on how much it’s helping. Old scores will be in square brackets

9:00 100% Will be listening to Grooveshark on my way in to work

10:00 98%! Not bad so far. Have been e-mailing lots (as my computer is currently out of action) and made a phone call

11:00 95% [92%] Still looking good, have sent plenty of e-mails and checking tweets and Facebook

12:00 90% Have only used 10% of the battery in 3 hours which isn’t bad considering the usage. I have still been e-mailing, Facebooking and tweeting since 11.

13:00 82% [78%] A bit of a jump here. I was listening to FM Radio on the walk back home for lunch and have been eBaying quite heavily (PKT Auctions app). I’ve noticed a few quirks with how JuiceDefender works. One example is that it will disable your volume keys when the screen is locked. This isn’t a huge problem unless you’re listening to music but it’s obviously one of the ways it saves your battery. (Phone usage should go back to normal after lunch as I have now fixed my computer ;))

14:00 78% Only light usage since the last update.

15:00 74% Again, haven’t used the phone much. Checked e-mail and tweets a few times.

16:00 71% More general use of the phone in the last hour, only lost 3%

17:00 69% [60%] Not bad going in the last hour, only down by 3%. Comparing this to the last test I can see that JuiceDefender has done a great job at saving me some power. Knowing that at the end of a working day and some quite heavy usage is reassuring. At the rate the phone has been discharging I know it could still get through a whole night out without being charged.

18:00 64% The walk home and some tweeting hasn’t caused a huge problem. Will be reporting again later on tonight.

22:45 53% left [34%] Well, nearly 14 hours on and I still have over half my battery left! I can certainly conclude from this initial test that JuiceDefender has done a great job at saving power on my phone. I will leave my phone on overnight and see what I end up with in the morning. (JuiceDefender will be disabled along with all syncing activities.)

Here's the proof!

[Update 04/02/2011] My phone has now been away from a power source for over 28.5 hours and I still have 18% left! I’ll see how long I can push it for the rest of the day!

[Update] I thought I’d include my Battery Saving Tips video now you’ve read through this article. It’ll show you how to save even more power when using your phone

[Update Oct 2011] I’ve also just reviewed this app on YouTube; you can check it out below
