Samsung/Google Nexus S Battery and Processor Drain Issue

This turned out to be very long post, go here if you just care for the summary, not the details!

Recently, I obtained my new (company) phone, Google Nexus S. I was very excited, because all reviews, statistics, etc. showed that it must be great, full with newest OS and functionalities device. I got the phone from DeliveryShop, who delivered it to me directly from USA’s BestBuy shops.

The first days I was quite happy pal, I had great, new toy to play with and I had not seen any issues so far. I loaded the phone with many apps, and it was behaving more than satisfactory. Plus, the device is very slick, with nice black, curved design. Very, very nice looking.

After few days with the phone I noticed the first issue: my contacts suddently became very slow to search through. It was taking literally 5-10 seconds after I type the name to get the first (not so narrow) results, and another 5-10 seconds to see actually what I was looking for. It seemed I was not alone: the same issue “My nexus S runs out of battery real fast and slows down on contact search” you can read at the Google Mobile forums (and more than once, actually). I was very astonished why this happens, I was also quite irritated. Come on, they’ve got to be kidding me to wait for more than 10 seconds for search! And on a phone, coming from the considered to be top SEARCH company in the world!

Two days later, however, I had more issues to worry about! My phone battery was draining like crazy. Imagine this scenario: I unplug my phone at 98-100% at 07:30, then I travel to work. When I sit on my desk at 08:15 (45 min later), my battery is at 88-90%. I.e., 10% for 45 minutes. Isn’t that just great?

The contacts issue was bad, but at leats bearable (to a degree). This second thing, however, seemed ridiculous! 4 hours battery live for top-notch 2011 model phone is just a big no-no! And I mean – BIG no-no!

The only thing I could research during the week was the phone’s battery report statistics. I saw that the app, which was draining the battery, was… “Android OS”. Great, isn’t it? And the phone tools so far (the system built-in tool and Processor Monitor Widget) did not give me any more information past that. And just “Android OS” using processor at 100% was not good and detailed enough information to me. I needed to know what’s exactly there, but I had no time to research the issue during the week (I noticed the problem Tuesday).
Additionally (and of course), the phone was getting quite warm. It was good, if I needed ellectrical pillow, but since this was just a phone, it was not good at all. The device was getting very warm just above the “Google(tm)” sign, where the camera was placed.

Three days later, however,
