iPhone 4 battery drain. Solved.

A quick follow up to

What I tried. Restore to 4.0.1 (not 4.0.2 or you will loose a jailbreak). Jailbreak. Install only MyWi4 from Cydia with Rock, run MyWi4, get the first license, remove MyWi4, install Elpelle6's MyWi4 without Rock, remove Rock - now you've got pretty clean jailbroken iPhone4 with MyWi4 without Rock installed. Run MyWi4 - it will ask you to respring. I told it "Later" and probably that what helps. It does work anyways - I tried it.

The battery runs out a little bit (I still believe MyWi4 is sorta dirty), but it's acceptable - under 5% overnight. Hopefully, it will work for you, too.

Peer reviews for self-improvement - PlusRated

We have recently started a new Web service. So I'm happy to invite all subscribers of my blog to it. To become one of the first our most valuable users, click at and register.

My team and I, we are huge believers that to be successful we need to know our weaknesses. It is just clueless to consider yourself to be a smart, efficient and pleasant person until somebody else does. And it doesn't matter that we often have people whom we don't care - there are always some whom we listen to and respect.
There are many ways to achieving this self-awaraness; however, the best way is simply just to ask politely. Ask our friends, colleagues, peers or managers a few simple questions: "Am I doing a good job managing my team? Am I a valuable asset to the company? How bad am I at organizing my time?". The more people we ask — the more objective the overall picture will be with respect to how we really are, how we behave, and how well we really do.

Intrigued yet?

We realized that there are many of you who want to self-improve, learn and grow; both from a career and personal perspective. That is why we have built PlusRated — the Web service that allows us to gather ratings and reviews from people with whom we know and stay in touch. PlusRated allows peers, colleagues and even friends to make an evaluation of your individual professional and social skills.
Self-awareness and knowledge is a very powerful means to achieve ambition and attain a more satisfying life as a whole. An every improvement begins with defining the starting point. So I urge you to get PlusRated for free now, to make your first step in learning yourself.

Welcome to PlusRated!

iPhone 4 jailbreak battery drain

I have recently used to make my iPhone 4 free. However, fairly soon, I've discovered that I have a significant battery drain with it. It took literally overnight to drop my 25% from fully charged one. So I decided to took few tries and find out who's responsible for this leak. On that particular jailbroken version, it was going down to 87% with 30 mins of usage and 3 hr 42 mins of standby time.

The clean restored iPhone stays for 32 mins of usage and 4 hr 47 mins of standby, and goes down to 95% only! That's more than 3 times. Not good.

Next, going thru the jailbreak, not touching Cydia or any apps. iPhone stays for 17 min of usage and 3 hr 35 mins and down to 96% only. Basically, that's a sign that jailbreak indeed doesn't drain the battery.

Next, installing all of the updates that Cydia wants you to. It took me overnight to measure it, but seeing 15 min of usage and 9 hr 33 mins of standby and down to 95% only is clearly a good indicator of no battery drain going on.

The last step was to install MyWi 4.3.4. It comes also with Mobile Subtrate. After spending some time with it - 1 hr 17 mins of usage and 5 hr 45 mins standby - brought my phone down to 78%, which is definitely stands out of the line of "good battery usage". So, either Mobile Subtrate is draining the battery or MyWi didn't do a good job writing an extension to it, and now it eats all he juice.

I'll keep you updated, but I'm already upset so much - the most important reason for me was free tethering - and now I feel that I'm paying too big premium for it.

Troubleshooting unlocked & jailbroken iPhone 4

For those who haven't tried yet. Jailbreak worked flawlessly on my iPhone 4. Unlock was relatively easy, too.

I also installed MyWi 4 (the major reason for actually jailbreaking my iPhone, I really need a device to tether on the way) and My3G. Besides, I've installed Open SSH server and SB Setting, to be able to turn the SSH server off. After that, problems started to appear. The biggest one was FaceTime turned off and not being able to turn on. It actually started to send freaking short messages to some +44 number (I guess I'd be quite upset with upcoming AT&T bill), and I started to receive some replies back. Installing iPhone Delivery (which was recommended to early users of jailbreak) didn't solve the problem. I stopped receiving replies (although, I'm not sure I'm not billed for them :), but FaceTime failed to activate.

Uninstalling My3G did the trick. Easily activated FaceTime after that, and it started to work well. Reinstalling My3G after, kept FaceTime activated, but every time I tried to connect thru FaceTime it was failing. So, I'm ending up with no My3G, which makes the overall experience less exciting, but I hope this problem can be solved soon.

Google Wave is heading to the dead pool

Wave has not seen the user adoption we would have liked. We don’t plan to continue developing Wave as a standalone product, but we will maintain the site at least through the end of the year and extend the technology for use in other Google projects.

Damn, that was so freaking easy to understand that Google Wave wasn't a product with a clear purpose. It wasn't solving any single problem. I was really surprised to see Google coming up with this product, where Product Management is taken into such high levels. Anyways, no regrets, hopefully it'll free up some space for something worth trying.
