Issue: How to Fix Battery Drain Issue After Windows 10 Anniversary Update?

I’ve installed Windows 10 Anniversary Update believing that it’s going to improve my laptop’s performance. However, the first thing I’ve noticed a day after the update that the battery life has dropped dramatically. Am I the only one who noticed this? Is it possible that this happens due to the update?

Solved Answer


Although Microsoft indicated a prolonged battery life as one of the best Windows 10 Anniversary Update features, it seems that it’s not working for all users. Thousands of people on the Windows-related forums are accusing Microsoft of false claims about extended battery life because right after successful installation of Anniversary update the lifespan of the battery decreased drastically. According to users, if their devices managed to keep up for 5 hours or even more, the update consumes so much battery power that the device runs for 2 hours only without a charge.

Although Microsoft has been dealing with battery draining issues on earlier Windows versions and released patches for this, it does not seem to be working on this problem with Windows Anniversary update. Therefore, if you have noticed a serious decrease of battery life after upgrading to Windows 10 Anniversary Update, you should try to fix this issue by yourself because no one knows if Microsoft is going to fix it some day.

Prevent websites, ISP, and other parties from tracking you

Private Internet Access is a VPN that can prevent your Internet Service Provider, the government, and third-parties from tracking your online and allow you to stay completely anonymous. The software provides dedicated servers for torrenting and streaming, ensuring optimal performance and not slowing you down. You can also bypass geo-restrictions and view such services as Netflix, BBC, Disney+, and other popular streaming services without limitations, regardless of where you are.

A VPN is also crucial when it comes to user privacy. Online trackers such as cookies can not only be used by social media platforms and other websites but also your Internet Service Provider and the government. Even if you apply the most secure settings via your web browser, you can still be tracked via apps that you are connected to the internet. Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speed.

Therefore, to stay completely anonymous and prevent the ISP and the government from spying on you, you should employ Private Internet Access VPN. It will allow you to connect to the internet while being completely anonymous, prevent trackers, ads, as well as malicious content. Most importantly, you will prevent the illegal surveillance activities that NSA and other governmental institutions are performing behind your back.


Recover your lost files quickly

Unforeseen circumstances can happen at any time while using the computer: it can turn off due to a power cut, a Blue Screen of Death (BSoD) can occur, or random Windows updates can decide to reboot the machine when you went away for a few minutes. As a result, your schoolwork, important documents, and other data might be lost.

Additionally, you might also be attacked by malware that can corrupt your Windows or encrypt files with a robust encryption algorithm, and ask for a ransom in Bitcoin for the decryption tool. Cybercriminals might not deliver what they promised, however, so it is better to attempt alternative file recovery methods that could help you to retrieve at least some portion of the lost data.

Data recovery software is one of the options that could help you recover your files. Once you delete a file, it does not vanish into thin air – it remains on your system as long as no new data is written on top of it. Data Recovery Pro is recovery software that searchers for working copies of deleted files within your hard drive. By using the tool, you can prevent loss of valuable documents, school work, personal pictures, and other crucial files.
