Nexus 5 battery drain on Android 6.0 Marshmallow

One of the improved features of Android 6.0 Marshmallow is improved battery life. Be it the Doze mode or the polishing of the rough edges of its predecessor, most people – at least the reviewers – seem to be noticing that their devices aren’t as thirsty for juice as they once used to. Unless you have a Nexus 5 or 6 that is.

I finally switched back the Nexus 5 couple of days ago and I immediately noticed how fast the battery of my phone drained. Today at work, I was down to the 30%s in no time. When I checked the battery status from the settings app, I notice something weird. The item that was using the highest percentage of battery was Wi-Fi. Why it is weird is because I did not have Wi-Fi enabled while I was away from work. So how could the Wi-Fi feature be responsible for draining the battery.

Google search – ironically in this case – came to my assist. It appears that there is a feature called Wi-Fi scanning in Marshmallow which helps improve the location by letting system apps and services detect Wi-Fi networks any time. I am not sure if it really helps with anything, but all I know is that I am not getting my whole day battery life anymore.

Is the battery of our MacBook Air dying?

After a long time, today I logged into my our MacBook Air to do some maintenance. I only use it for that: OS updates and stuff.

There was an OS update (I cannot recall the version number because I have no interest in this OS) so I kept the power adapter plugged in because I expected it to take a while. I didn't take long, but I let it charge through to 100%. After a while I attended back to it and clicked on the battery icon in the menu bar near clock. (Again I cannot recall why I did that.)

There was a notification saying "Service battery" with an exclamation mark next to it in the info tray that was pulled down when clicked on the battery icon.

This was the first time I had seen such notification. Did you notice that it said 2:05 remaining? Just 2:05 with a 94% charge? Something must be up!

iOS 6.1.2 released and can be jailbroken using evasi0n 1.4

Apple released iOS 6.1.1 just a week or do ago to fix 3G connectivity related issues specifically on the iPhone 4S, but it did fix the Exchange bug nor the battery drain issue that iOS 6.1 introduced. Instead, 6.1.1 brought back a serious flaw that was present in the old days that allowed anyone to bypass the password lock screen without entering the password. 

The trick is a bit hard to do, and I haven't tried it. But here's how you do it.

Today Apple released iOS 6.1.2 which fixes all these 3 issues. That's all good and all, but what about the state of jail breaking? Does 6.1.2 patch the vulnerability that allowed evasi0n jailbreak to pwn iOS 6.1?

Not so. The evasi0n jailbreak tool has been already upgraded to version 1.4 which allows you to jailbreak 6.1.2. Head to this link if you already don't know the procedure.

Edit:

Some say the password bypass bug is fixed, some say it is not. I hope it is fixed because I don't want Apple to release updates every week which might eventually block evasi0n tool. :/
