Is TNB down right now?
The panel above shows the live TNB status for the app and the account portal. Fresh TNB down reports from other account holders appear there through the day. A quiet panel points to a fault on your own phone or account. A busy panel points to a wider problem at TNB. Open the app once more after reading the panel.
Reports often jump when a fresh bill run lands and thousands open the app together. The bill page then loads slowly or shows a plain error. Waiting a short while clears most of those peaks. A steady stream of reports all day means the platform itself needs work.
Is TNB down for me or everyone?
Start with a second device on a different connection, such as a phone on mobile data. If myTNB opens there, your home network or app copy is at fault. If both devices fail in the same way, the problem sits with TNB for everyone.
Checking your electricity use on the usage graph
The usage graph compares your electricity use across recent billing cycles in one picture. Bars climb in hot spells when air conditioning runs for long hours. A flat or missing graph often means the latest meter reading has not landed yet. The graph refreshes after the new bill is issued.
Tap a single cycle to see the units and the charge for that period. That view helps explain a bill that feels higher than usual. It also shows if an estimated reading drove the amount. Keep the graph in mind before you query a charge.
Paying a bill with a saved card
Saved cards speed up payment since the card details stay stored after the first use. Enter the amount, confirm the account, then approve the bank prompt. A payment that stops at the bank prompt usually fails on the bank side. The history screen should show the settled bill soon after.
Reporting a power cut inside myTNB
The app carries a report flow for homes left without power. During a TNB outage on your street, send the report once and keep the reference it gives back. Repeat reports for the same address do not speed up the repair crew. The status line on the home screen changes as work starts.
Linking more than one TNB account
One login can hold several accounts, handy for a family home plus a rental unit. Add each account number from its latest bill, then name it in your own words. Each linked account keeps its own bill and usage graph. Switching between accounts happens from the account list on the home screen.
Common TNB Problems and Fixes
Most myTNB faults clear with a few checks on the account, the app copy and your connection.
Bill detail page shows a zero amount
Reopen the bill from the account list instead of the notification. If the amount still reads zero, sign out and back in. A zero after that means the billing run has not finished.
Usage graph stays blank after login
Give the graph a full minute on a strong connection before tapping again. Clear the app cache if older cycles show but the newest stays blank.
Saved card payment stops halfway
Check the bank prompt first, since a missed approval kills the payment. Remove the saved card and add it again if the stop repeats. The bill stays unpaid until the history screen lists the payment.
Login loops back to the start
Type the password by hand instead of pasting it from a note. Reset the password inside the app if the loop survives a fresh type.
New bill alert never arrives
Open notification settings for the app and allow alerts for bills. Then check the promotions folder of your email. The bill itself still sits inside the app even when the alert fails.

Frequently Asked Questions
How do I check my TNB bill in the app?
Open the account on the home screen and tap the bill entry. The latest amount, due date and full bill copy sit on that screen.
Why does my usage graph look higher than last cycle?
Hot spells push air conditioning use up, and the graph follows real meter readings. Compare the units, not just the charge, for a fair check.
What should I do if a payment leaves my bank but the bill stays open?
Wait for the history screen to update, then check the same account again. Keep the bank receipt until the payment line appears in the app.
Can I hold two homes under one myTNB login?
Both fit under one login. Link each account number from its own bill and give each home a clear name. Bills and graphs stay separate inside the list.
Where do I report a power cut in myTNB?
Use the report flow on the home screen and send your address once. Keep the reference the app gives back for later checks.
When does a new bill appear in the app?
A fresh bill lands after the meter reading for your cycle closes. The alert follows soon after the bill posts to your account.
